weight[mass]and typically width and length,commonly classified as follows:3.1.1.1When Ordered to Thickness:(1)Over8in.[200mm]in width and0.230in.or over [over6mm]in thickness.(2)Over48in.[1200mm]in width and0.180in.or over [over4.5mm]in thickness.3.1.1.2When Ordered to Weight[Mass]:(1)Over8in.[200mm]in width and9.392lb/ft2[47.10 kg/m2]or heavier.(2)Over48in.[1200mm]in width and7.350lb/ft2[35.32 kg/m2]or heavier.3.1.1.3Discussion—Steel products are available in various thickness,width,and length combinations depending upon equipment and processing capabilities of various manufactur-ers and processors.Historic limitations of a product based upon dimensions(thickness,width,and length)do not take into account current production and processing capabilities.To qualify any product to a particular product specification re-quires all appropriate and necessary tests be performed and that the results meet the limits prescribed in that product specifi-cation.If the necessary tests required by a product specification cannot be conducted,the product cannot be qualified to that specification.This general requirement standard contains per-mitted variations for the commonly available sizes.Permitted variations for other sizes are subject to agreement between the customer and the manufacturer or processor,whichever is applicable.3.1.1.4Slabs,sheet bars,and skelp,though frequently falling in the foregoing size ranges,are not classed as plates.3.1.1.5Coils are excluded from qualification to the appli-cable product specification until they are decoiled,leveled or straightened,formed(if applicable),cut to length,and,if required,properly tested by the processor in accordance with ASTM specification requirements(see Sections9,10,11,12, 13,14,15,18,and19and the applicable product specification).3.1.2Shapes(Flanged Sections):3.1.2.1structural-size shapes—rolledflanged sections hav-ing at least one dimension of the cross section3in.[75mm]or greater.3For

shapes—rolledflanged sections having a maximum dimension of the cross section less than3in.[75 mm].3.1.2.3“W”shapes—doubly-symmetric,wide-flange shapes with insideflange surfaces that are substantially paral-lel.3.1.2.4“HP”shapes—are wide-flange shapes generally used as bearing piles whoseflanges and webs are of the same nominal thickness and whose depth and width are essentially the same.3.1.2.5“S”shapes—doubly-symmetric beam shapes with insideflange surfaces that have a slope of approximately162⁄3 %.3.1.2.6“M”shapes—doubly-symmetric shapes that cannot be classified as“W,”“S,”or“HP”shapes.3.1.2.7“C”shapes—channels with insideflange surfaces that have a slope of approximately162⁄3%.3.1.2.8“MC”shapes—channels that cannot be classified as “C”shapes.3.1.2.9“L”shapes—shapes having equal-leg and unequal-leg angles.3.1.3sheet piling—rolled steel sections that are capable of being interlocked,forming a continuous wall when individual pieces are driven side by side.3.1.4bars—rounds,squares,and hexagons,of all sizes;flats 13⁄64in.(0.203in.)and over[over5mm]in specified thickness, not over6in.[150mm]in specified width;andflats0.230in. and over[over6mm]in specified thickness,over6to8in. [150to200mm]inclusive,in specified width.3.1.5exclusive—when used in relation to ranges,as for ranges of thickness in the tables of permissible variations in dimensions,is intended to exclude only the greater value of the range.Thus,a range from60to72in.[1500to1800mm] exclusive includes60in.[1500mm],but does not include72 in.[1800mm].3.1.6rimmed steel—steel containing sufficient oxygen to give a continuous evolution of carbon monoxide during sol-dification,resulting in a case or rim of metal virtually free of voids.3.1.7semi-killed steel—incompletely deoxidized steel con-taining sufficient oxygen to form enough carbon monoxide during solidification to offset solidification shrinkage.3.1.8capped steel—rimmed steel in which the rimming action is limited by an early capping operation.Capping is carried out mechanically by using a heavy metal cap on a bottle-top mold or chemically by an addition of aluminum or ferrosilicon to the top of the molten steel in an open-top mold.3.1.9killed steel—steel deoxidized,either by addition of strong deoxidizing agents or by vacuum treatment,to reduce the oxygen content to such a level that no reaction occurs between carbon and oxygen during solidification.3.1.10mill edge—the normal edge produced by rolling between horizontalfinishing rolls.A mill edge does not conform to any definite l edge plates have two mill edges and two trimmed edges.3.1.11universal mill edge—the normal edge produced by rolling between horizontal and verticalfinishing rolls.Univer-sal mill plates,sometimes designated UM Plates,have two universal mill edges and two trimmed edges.3.1.12sheared edge—the normal edge produced by shear-ing.Sheared edge plates are trimmed on all edges.3.1.13gas cut edge—the edge produced by gasflame cutting.3.1.14special cut edge—usually the edge produced by gas flame cutting involving special practices such as pre-heating or post-heating,or both,in order to minimize stresses,avoid thermal cracking and reduce the hardness of the gas cut edge. In special instances,special cut edge is used to designate an edge produced by machining.3.1.15sketch—when used to describe a form of plate, denotes a plate other than rectangular,circular,or semi-circular.Sketch plates may be furnished to a radius or with four or more straight sides.3.1.16normalizing—a heat treating process in which a steel plate is reheated to a uniform temperature above the upper critical temperature and then cooled in air to below the transformation range.3.1.17plate-as-rolled—when used in relation to the loca-tion and number of tests,the term refers to the unit plate rolled from a slab or directly from an ingot.It does not refer to the condition of the plate.3.1.18fine grain practice—a steelmaking practice that is intended to produce a killed steel that is capable of meeting the requirements forfine austenitic grain size.3.1.18.1Discussion—It normally involves the addition of one or more austenitic grain refining elements in amounts that have been established by the steel producer as being sufficient. Austenitic grain refining elements include,but are not limited to,aluminum,columbium,titanium,and vanadium.3.1.19structural product—a hot-rolled steel plate,shape, sheet piling,or bar.3.1.20coil—hot-rolled steel in coiled form that is intended to be processed into afinished structural product.3.1.21manufacturer—the organization that directly con-trols the conversion of steel ingots,slabs,blooms,or billets,by hot-rolling,into an as-rolled structural product or into coil;and for structural products produced from as-rolled structural products,the organization that directly controls,or is respon-sible for,the operations involved infinishing the structural product.3.1.21.1Discussion—Suchfinishing operations include lev-eling or straightening,hot forming or cold forming(if appli-cable),welding(if applicable),cutting to length,testing, inspection,conditioning,heat treatment(if applicable),pack-aging,marking,loading for shipment,and certification.3.1.22processor—the organization that directly controls,or is responsible for,the operations involved in the processing of coil into afinished structural product.Such processing opera-tions include decoiling,leveling or straightening,hot-forming or cold-forming(if applicable),welding(if applicable),cutting to length,testing,inspection,conditioning,heat treatment(if applicable),packaging,marking,loading for shipment,and certification.3.1.22.1Discussion—The processing operations need not be done by the organization that did the hot rolling of thecoil.If only one organization is involved in the hot rolling and processing operations,that organization is termed the manu-facturer for the hot rolling operation and the processor for the processing operations.If more than one organization is in-volved in the hot rolling and processing operations,the organization that did the hot rolling is termed the manufacturer and an organization that does one or more processing opera-tions is termed a processor.4.Ordering Information4.1Information items to be considered,if appropriate,for inclusion in purchase orders are as follows:4.1.1ASTM product specification designation(see1.1)and

open-hearth,basic-oxygen, or electric-arc furnace,possibly followed by additionl refining in a ladle metallurgy furnace(LMF),or secondary melting by vacuum-arc remelting(V AR)or electroslag remelting(ESR).5.2The steel shall be strand cast or cast in stationary molds.5.2.1Strand Cast:5.2.1.1When heats of the same nominal chemical compo-sition are consecutively strand cast at one time,the heat number assigned to the cast product need not be changed until all of the steel in the cast product is from the following heat.5.2.1.2When two consecutively strand cast heats have different nominal chemical composition ranges,the manufac-turer shall remove the transition material by an established procedure that positively separates the grades.5.3Structural products shall be produced from an as-rolled structural product or from coil.5.4Where part of a heat is rolled into an as-rolled structural product and the balance of the heat is rolled into coil,each part shall be tested separately.5.5Structural products produced from coil shall not contain splice welds,unless previously approved by the purchaser.6.Heat Treatment6.1Where th structural product is required to be heat treated,such heat treatment shall be performed by the manu-facturer,the processor,or the fabricator,unless otherwise specified in the applicable product specification.N OTE2—When no heat treatment is required,the manufacturer or processor has the option of heat treating the structural product by normalizing,stress relieving,or normalizing then stress relieving to meet the applicable product specification.6.2Where the heat treatment is to be performed by other than the manufacturer,the order shall so state.6.2.1Where the heat treatment is to be performed by other than the manufacturer,the structural products shall be accepted on the basis of tests made on test specimens taken from full thickness test coupons heat treated in accordance with the requirements specified in the applicable product specification or in the purchase order.If the heat-treatment temperatures are not specified,the manufacturer or processor shall heat treat the test coupons under conditions he considers appropriate,pro-vided that the purchaser is informed of the procedure followed in heat treating the test coupons.6.3Where the heat treatment is to be performed by the manufacturer or the processor,the structural product shall be heat treated as specified in the applicable product specification, or as specified in the purchase order,provided that the heat treatment specified by the purchaser is not in conflict with the requirements of the applicable product specification.6.4Where normalizing is to be performed by the fabricator, the structural product shall be either normalized or heated uniformly for hot forming,provided that the temperature to which the structural product is heated for hot forming does not significantly exceed the normalizing temperature.6.5The use of cooling rates that are faster than those obtained by cooling in air to improve the toughness shall be subject to approval by the purchaser,and structural products so treated shall be tempered subsequently in the range from1100 to1300°F[595to705°C].7.Chemical Analysis7.1Heat Analysis:7.1.1Sampling for chemical analysis and methods of analy-sis shall be in accordance with Test Methods,Practices,and Terminolgy A751.7.1.2For each heat,the heat analysis shall include determi-nation of the content of carbon,manganese,phosphorus,sulfur, silicon,nickel,chromium,molybdenum,copper,vanadium, columbium;any other element that is specified or restricted by the applicable product specification for the applicable grade, class,and type;and any austenitic grain refining element whose content is to be used in place of austenitic grain size testing of the heat(see8.3.2).7.1.3Except as allowed by7.1.4for primary heats,heat analyses shall conform to the heat analysis requirements of the applicable product specification for the applicable grade,class, andtype.7.1.4Where vacuum-arc remelting or electroslag remelting is used,a remelted heat is defined as all ingots remelted from a single primary heat.If the heat analysis of the primary heat conforms to the heat analysis requirements of the applicable product specification for the applicable grade,class,and type, the heat analysis for the remelted heat shall be determined from one test sample taken from one remelted ingot,or the product of one remelted ingot,from the primary heat.If the heat analysis of the primary heat does not conform to the heat analysis requirements of the applicable product specification for the applicable grade,type,and class,the heat analysis for the remelted heat shall be determined from one test sample taken from each remelted ingot,or the product of each remelted ingot,from the primary heat.7.2Product Analysis—For each heat,the purchaser shall have the option of analyzing representative samples taken from thefinished structural product.Sampling for chemical analysis and methods of analysis shall be in accordance with Test Methods,Practices,and Terminology A751.The product analyses so determined shall conform to the heat analysis requirements of the applicable product specification for the applicable grade,class,and type,subject to the permitted variations in product analysis given in Table A.If a range is specified,the determinations of any element in a heat shall not vary both above and below the specified range.Rimmed or capped steel is characterized by a lack of homogeneity in its composition,especially for the elements carbon,phosphorus, and sulfur.Therefore,the limitations for these elements shall not be applicable unless misapplication is clearly indicated.7.3Referee Analysis—For referee purposes,Test Methods, Practices,and Terminology A751shall be used.7.4Grade Substitution—Alloy steel grades that meet the chemical requirements of Table1of Specification A829shall not be substituted for carbon steel grades.8.Metallurgical Structure8.1Where austenitic grain size testing is required,such testing shall be in accordance with Test Methods E112and at least70%of the grains in the area examined shall meet the specified grain size requirement.8.2Coarse Austenitic Grain Size—Where coarse austenitic grain size is specified,one austenitic grain size test per heat

allowed in8.3.2,one austenitic grain size test per heat shall be made and the austenitic grain size number so determined shall be5or higher.N OTE3—Such austenitic grain size numbers may be achieved with lower contents of austenitic grain refining elemenst than8.3.2requires for austenitic grain size testing to be waived.8.3.2Unless testing forfine austenitic grain size is specified in the purchase order,an austenitic grain size test need not be made for any heat that has,by heat analysis,one or more of the following:8.3.2.1A total aluminum content of0.020%or more. 8.3.2.2An acid soluble aluminum content of0.015%or more.8.3.2.3A content for an austenitic grain refining element that exceeds the minimum value agreed to by the purchaser as being sufficient for austenitic grain size testing to be waived,or 8.3.2.4Contents for the combination of two or more auste-nitic grain refining elements that exceed the applicable mini-mum values agreed to by the purchaser as being sufficient for austenitic grain size testing to be waived.9.Quality9.1General—Structural products shall be free of injurious defects and shall have a workmanlikefinish.N OTE4—Unless otherwise specified,structural products are normally furnished in the as-rolled condition and are subjected to visual inspection by the manufacturer or processor.Non-injurious surface or internal imperfections,or both,may be present in the structural product as delivered and the structural product may require conditioning by the purchaser to improve its appearance or in preparation for welding,coating, or other further operations.More restrictive requirements may be specified by invoking supplemen-tary requirements or by agreement between the purchaser and the supplier. Structural products that exhibit injurious defects during subsequent fabrication are deemed not to comply with the applicable product specification.(See17.2.)Fabricators should be aware that cracks may initiate upon bending a sheared or burned edge during the fabrication process;this is not considered to be a fault of the steel but is rather a function of the induced cold-work or the heat-affected zone.The conditioning requirements in9.2,9.3,and9.4limit the condition-ing allowed to be performed by the manufacturer or processor.Condition-ing of imperfections beyond the limits of9.2,9.3,and9.4may be performed by parties other than the manufacturer or processor at the discretion of thepurchaser.TABLE A Permitted Variations in Product AnalysisN OTE1—Where“...”appears in this table,there is no requirement.ElementUpper Limit,orMaximum SpecifiedValue,%Permitted Varia-tions,%UnderMinimumLimitOverMaximumLimitCarbon to0.15incl0.020.03over0.15to0.40incl0.030.04over0.40to0.75incl0.040.05over0.750.040.06 Manganese A to0.60incl0.050.06over0.60to0.90incl0.060.08over0.90to1.20incl0.080.10over1.20to1.35incl0.090.11over1.35to1.65incl0.090.12over1.65to1.95incl0.110.14over1.950.120.16Phosphorus to0.04inclover0.04to0.15incl ......0.010BSulfur to0.06inclover0.06...B0.010BSilicon to0.30inclover0.30to0.40inclover0.40to2.20incl 0.020.050.060.030.050.06Nickel to1.00incl0.030.03over1.00to2.00incl0.050.05over2.00to3.75incl0.070.07over3.75to5.30incl0.080.08over5.300.100.10Chromium to0.90inclover0.90to2.00inclover2.00to4.00incl 0.040.060.100.040.060.10Molybdenum to0.20inclover0.20to0.40inclover0.40to1.15incl 0.010.030.040.010.030.04Copper0.20minimum onlyto1.00inclover1.00to2.00incl 0.020.030.05...0.030.05Titanium to0.10incl0.01C0.01Vanadium to0.10incl0.01C0.01over0.10to0.25incl0.020.02over0.250.020.03minimum only specified0.01...Boron any B B Columbium to0.10incl0.01C0.01 Zirconium to0.15incl0.030.03Nitrogen to0.030incl0.0050.005A Permitted variations in manganese content for bars and bar size shapes shall be:to0.90incl60.03;over0.90to2.20incl60.06.B Product analysis not applicable.C0.005,if the minimum of the range is0.01%.Index to Tables of Permitted VariationsDimensionTableInch-PoundUnitsSI UnitsCamberPlates,Carbon Steel;Sheared and Gas-Cut12A1.12 Plates,Carbon Steel;Universal Mill11A1.11 Plates,Other than Carbon Steel;Sheared,11A1.11 Gas-Cut and Universal MillShapes,Rolled;S,M,C,MC,and L21A1.21 Shapes,Rolled;W and HP24A1.24 Shapes,Split;L and T25A1.25 Cross Section of Shapes and BarsFlats26A1.26 Hexagons28A1.28 Rounds and Squares27A1.27 Shapes,Rolled;L,Bulb Angles,and Z17A1.17 Shapes,Rolled;W,HP,S,M,C,and MC16A1.16 Shapes,Rolled;T18A1.18 Shapes,Split;L and T25A1.25 DiameterPlates,Sheared6A1.6 Plates,Other than Alloy Steel,Gas-Cut7A1.7 Plates,Alloy Steel,Gas-Cut10A1.10 Rounds27A1.27 End Out-of-SquareShapes,Other than W20A1.20 Shapes,W22A1.22 Shapes,Milled,Other than W23A1.23 FlatnessPlates,Carbon Steel13A1.13 Plates,Other than Carbon Steel14A1.14 Plates,Restrictive—Carbon Steel S27.1S27.2 Plates,Restrictive—Other than Carbon Steel S27.3S27.4 LengthBars30A1.30 Bars,Recut31A1.31 Plates,Sheared and Universal Mill3A1.3 Plates,Other than Alloy Steel,Gas-Cut9A1.9 Plates,Alloy Steel,Gas-Cut8A1.8 Plates,Mill Edge4A1.4 Shapes,Rolled;Other than W19A1.19 Shapes,Rolled;W and HP22A1.22 Shapes,Split;L and T25A1.25 Shapes,Milled23A1.23 StraightnessBarsShapes,Other than W2921A1.29A1.21 SweepShapes,W and HP24A1.24 ThicknessFlatsPlates,Ordered to Thickness261A1.26A1.1 WavinessPlates15A1.15 Weight[Mass]Plates,Ordered to Weight[Mass]2A1.2 WidthFlats26A1.26 Plates,Sheared3A1.3 Plates,Universal Mill5A1.5 Plates,Other than Alloy Steel,Gas-Cut9A1.9 Plates,Alloy Steel,Gas-Cut8A1.8 Plates,Mill Edge4A1.4。

Designation:A749/A749M–97(Reapproved2002)Standard Specification forSteel,Strip,Carbon and High-Strength,Low-Alloy,Hot-Rolled,General Requirements for1This standard is issued under thefixed designation A749/A749M;the number immediately following the designation indicates the year of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon(e)indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1.Scope1.1This specification covers the general requirements for hot-rolled steel strip in coils and cut lengths.It applies to carbon steel and high-strength,low-alloy steel furnished as hot-rolled.1.2This specification is not applicable to hot-rolled heavy-thickness carbon sheet and strip coils(ASTM Specification A635/A635M),cold-rolled carbon steel strip(ASTM Speci-fication A109or A109M),high-strength,low-alloy cold-rolled steel(ASTM Specifications A606and A607)or cold-rolled carbon spring steel(ASTM Specification A682or A682M).1.3In case of any conflict in requirements,the requirements of the individual material specification shall prevail over those of this general specification.1.4For the purposes of determining conformance with this and the appropriate product specification referenced under2.1, values shall be rounded to the nearest unit in the right hand place offigures used in expressing the limiting values in accordance with the rounding method of Practice E29.1.5Annex A1lists permissible variations in dimensions and mass(Note1)in SI[metric]units.The values listed are not exact conversions of the values listed in the inch-pound tables, but instead are rounded or rationalized values.Conformance to Annex A1is mandatory when the“M”specification is used. N OTE1—The term“weight”is used when inch-pound units are the standard;however,under SI,the preferred term is“mass.”1.6The values stated in either inch-pound units or SI units are to be regarded as standard.Within the text,the SI units are shown in brackets.The values stated in each system are not exact equivalents;therefore,each system must be used inde-pendently of the bining values from the two systems may result in nonconformance with the specification.1.7This specification and the applicable material specifica-tions are expressed in both inch-pound units and SI units.However,unless the order specifies the applicable“M”speci-fication designation(SI units),the material shall be furnished to inch-pound units.2.Referenced Documents2.1ASTM Standards:A109Specification for Steel,Strip,Carbon,Cold-Rolled2 A109M Specification for Steel,Strip,Carbon,Cold-Rolled (Metric)2A370Test Methods and Definitions for Mechanical Testing of Steel Products2A606Specification for Steel,Sheet and Strip,High-Strength,Low-Alloy,Hot-Rolled and Cold-Rolled,with Improved Atmospheric Corrosion Resistance2A607Specification for Steel,Sheet and Strip,High-Strength,Low-Alloy,Columbium or Vanadium,or Both, Hot-Rolled and Cold-Rolled2A635/A635M Specification for Steel,Sheet and Strip, Heavy-Thickness Coils,Carbon,Hot-Rolled2A682Specification for Steel,Strip,High-Carbon,Cold-Rolled,Spring Quality,General Requirements For2A682M Specification for Steel,Strip,High-Carbon,Cold-Rolled,Spring Quality,General Requirements For(Met-ric)2A700Practices for Packaging,Marking,and Loading Methods for Steel Products for Domestic Shipment3A751Test Methods,Practices,and Terminology for Chemical Analysis of Steel Products2E11Specification for Wire-Cloth Sieves for Testing Pur-poses4E29Practice for Using Significant Digits in Test Data to Determine Conformance with Specifications4E290Test Method for Semi-Guided Bend Test for Ductility of Metallic Materials52.2Military Standards:61This specification is under the jurisdiction of ASTM Committee A01on Steel, Stainless Steel,and Related Alloys,and is the direct responsibility of Subcommittee A01.19on Steel Sheet and Strip.Current edition approved November10,2002.Published January2003.Origi-nally approved st previous edition approved in1997as A749–97.2Annual Book of ASTM Standards,V ol01.03.3Annual Book of ASTM Standards,V ol01.05.4Annual Book of ASTM Standards,V ol14.02.5Annual Book of ASTM Standards,V ol03.01.6Available from Standardization Documents Order Desk,Bldg.4Section D,700 Robbins Ave.,Philadelphia,PA19111-5094,Attn:NPODS.1Copyright©ASTM International,100Barr Harbor Drive,PO Box C700,West Conshohocken,PA19428-2959,United States.MIL-STD-129Marking for Shipment and StorageMIL-STD-163Steel Mill Products,Preparation for Ship-ment and Storage2.3Federal Standards:6Fed.Std.No.123Marking for Shipments(Civil Agencies) Fed.Std.No.183Continuous Identification Marking of Iron and Steel Products3.Terminology3.1Definitions of Terms Specific to This Standard:Descrip-tions of Terms Specific to This Standard:3.1.1Steel Types:3.1.2carbon steel—the designation for steel when no mini-mum content is specified or required for aluminum,chromium, cobalt,columbium,molybdenum,nickel,titanium,tungsten, vanadium,zirconium,or any element added to obtain a desired alloying effect;when the specified minimum for copper does not exceed0.40%;or when the maximum content specified for any of the following elements does not exceed the percentages noted;manganese1.65,silicon0.60,or copper0.60.

The sampling may be facilitated by folding the strip both ways, so that several samples may be taken at one drilling.Steel subjected to certain heating operations by the purchaser may not give chemical analysis results that properly represent its original composition.Therefore,users must analyze chips taken from the steel in the condition in which it is received from the steel manufacturer.5.5Specimen Preparation—Drillings or chips must be taken without the application of water,oil,or other lubricant, and must be free of scale,grease,dirt,or other foreign substances.They must not be overheated during cutting to the extent of causing decarburization.Chips must be well mixed, and those too coarse to pass a No.10(2.00-mm)sieve or too fine to remain on a No.30(600-µm)sieve are not suitable for proper analysis.Sieve size numbers are in accordance with Specification E11.5.6Test Methods—In case a referee analysis is required and agreed upon to resolve a dispute concerning the results of a chemical analysis,the procedure for performing the referee analysis must be in accordance with the latest issue of Test Methods,Practices,and Terminology A751,unless otherwise agreed upon between the manufacturer and the purchaser.6.Mechanical Properties6.1The mechanical property requirements,number of specimens,test locations,and specimen orientation shall be in accordance with the applicable product specification.6.2Unless otherwise specified in the applicable product specification,test specimens must be prepared in accordance with Test Methods and Definitions A370.6.3Mechanical tests shall be conducted in accordance with Test Methods and Definitions A370.6.4Bend tests,where required,shall be conducted in compliance with Test Methods E290.6.5To determine conformance with the product specifica-tion,a calculated value should be rounded to the nearest1ksi [7MPa]tensile strength and yield point or yield strength,and to the nearest unit in the right hand place offigures used in expressing the limiting value for other values in accordance with the rounding off method given in Practice E29.6.6Structural steels are commonly fabricated by cold bend-ing.There are many interrelated factors that affect the ability of a given steel to cold form over a given radius under shop conditions.These factors include thickness,strength level, degree of restraint,relationship to rolling direction,chemistry, and microstructure.Each of the appropriate product specifica-tions lists in the appendix the suggested minimum inside radius for cold bending.These radii should be used as minima for90°bends.They presuppose“hard way”bending(bend axis parallel to rolling direction)and reasonably good shop forming practices.Where possible,the use of larger radii or“easy way”bends are recommended for improved performance.7.7Fabricators should be aware that cracks may initiate upon bending a sheared or burned edge.This is not considered to be a fault of the steel but is rather a function of the induced cold-work or heat-affected zone.7.Dimensions,Tolerances,and Allowances7.1Dimensions,tolerances,and allowances applicable to products covered by this specification are contained in Tables 2-9[Annex A1,Tables A1.1-A1.7].The appropriate tolerance tables shall be identified in each individual specification.8.Workmanship8.1Cut lengths shall have a workmanlike appearance and shall not have imperfections of a nature or degree for the product,the grade,and the quality ordered that will be detrimental to the fabrication of thefinished part.8.2Coils may contain some abnormal imperfections that render a portion of the coil unusable since the inspection of coils does not afford the producer the same opportunity to remove portions containing imperfections as in the case with cut lengths.9.Finish and Condition9.1Hot-rolled strip has a surface with an oxide or scale resulting from the hot-rolling operation.The oxide or scale can be removed by pickling or blast cleaning when required for press-work operations or welding.Hot-rolled and hot-rolled descaled strip are not generally used for exposed parts where surface is of prime importance.However,hot-rolled surface might be of importance,as in the case of weathering steels for exposed parts.9.1.1Hot-rolled strip can be supplied with mill edges, square edges,or cut(slit)edges as specified.9.1.1.1Mill edges are the natural edges resulting from the hot-rolling operation and are generally round and smooth without any definite contour.9.1.1.2Square edges are the edges resulting from rolling through vertical edging rolls during the hot-rolling operations. These edges are square and smooth,with the corners slightly rounded.9.1.1.3Cut(slit)edges are the normal edges that result from the shearing,slitting,or trimming of mill edges.9.1.2The ends of plain hot-rolled mill-edge coils are irregular in shape and are referred to as uncropped ends.Where such ends are not acceptable,the purchaser’s order should so specify.Processed coils such as pickled or blast cleaned are supplied with square-cut ends.9.2Oiling:TABLE2Index of Tables for Dimensions,Tolerances,andAllowancesDimensions Table No.Inch-Pound UnitsSI UnitsCamber tolerances8A1.6Crown tolerances5A1.3Flatness tolerances9A1.7Length tolerances7A1.5 Thickness tolerances3,4A1.1,A1.2 Width tolerances6A1.49.2.1Plain hot-rolled strip is customarily furnished notoiled.Oiling must be specified when required9.2.2Hot-rolled pickled or descaled strip is customarily furnished oiled.If the product is not to be oiled,it must be so specified since the cleaned surface is prone to rusting.10.General Requirements for Delivery10.1Products covered by this specification are produced to inch-pound or metric decimal thickness only.10.2Steel may be produced as ingot-cast or strand-cast. When different grades of strand-cast steel are sequentially cast, identification and separation of the transition material is required.11.Retests11.1If any test specimen shows defective machining or developsflaws,it must be discarded and another specimen substituted.11.2If the percentage of elongation of any tension test specimen is less than that specified and any part of the fracture is more than3⁄4in.[20mm]from the center of the gage length of a2-in.[50mm]specimen or is outside the middle half of the gage length of an8-in.[200mm]specimen,as indicated by scribe scratches marked on the specimen before testing,a retest is allowed.11.3If a bend specimen fails,due to conditions of bending more severe than required by the specification,a retest is permitted either on a duplicate specimen or on a remaining portion of the failed specimen.12.Inspection12.1When the purchaser’s order stipulates that inspection and test(except product analyses)for acceptance on the steel be made prior to shipment from the mill,the manufacturer shall afford the purchaser’s inspector all reasonable facilities toTABLE3Thickness Tolerances of Hot-Rolled Strip A(Carbon and High-Strength,Low-Alloy Steel)Ordered to Nominal Thickness(Coils and Cut Lengths,Including Pickled)N OTE1—Micrometres used for measurement of thickness shall be constructed with eitherflat anvils having a minimum diameter of0.188in.or rounded anvils having a minimum radius of curvature of0.100in.Micrometres with pointed anvils are not suitable for thickness measurement.Specified Width,in.Thickness Tolerance,Over and Under,in.,for Specified Nominal Thickness,in.Over Through Through0.057Over0.057to0.118,inclOver0.118to0.187,inclOver0.187to0.203,inclOver0.203to0.230,excl...3½0.0030.0040.0050.006...3½60.0030.0050.0050.006...6120.0040.0050.0050.0060.006A Measurements for the above table are taken"in.from the edge of a strip on1in.or wider;and at any place on the strip when narrower than1in.The given tolerances do not include crown and therefore the tolerances for crown as shown in Table5are in addition to tolerances in Table3.TABLE4Thickness Tolerances of Hot-Rolled Strip A(Carbon and High-Strength,Low-Alloy Steel)Ordered to Minimum Thickness(Coils and Cut Lengths,Including Pickling)N OTE1—Micrometres used for measurement of thickness shall be constructed with eitherflat anvils having a minimum diameter of0.188in.or rounded anvils having a minimum radius of curvature of0.100in.Micrometres with pointed anvils are not suitable for thickness measurement.Specified Width,in.Thickness Tolerance,Over Only,for Specified Minimum Thickness,in.Over Through Through0.057Over0.057to0.118,inclOver0.118to0.187,inclOver0.187to0.203,inclOver0.203to0.230,excl...31⁄20.0060.0080.0100.012...31⁄260.0060.0100.0100.012...6120.0080.0100.0100.0120.012A Measurements for the above table are taken"in.from the edge of a strip on1in.or wider;and at any place on the strip when narrower than1in.The given tolerances do not include crown and therefore the tolerances for crown as shown in Table5are in addition to tolerances in Table4Table4.TABLE5Crown Tolerances of Hot-Rolled Strip(Carbon andHigh-Strength,Low-Alloy Steel)(Coils and Cut Lengths,Including Pickled)Strip may be thicker at the center than at a point3⁄8in.from theedge by the following amounts:Specified Width,in.Crown Tolerance,Over Only,for SpecifiedMinimum Thickness,in.Over Through Through0.118Over0.118to0.187,inclOver0.187to0.230,excl...31⁄20.0020.0020.001 31⁄260.0030.0020.002 6120.0040.0030.003TABLE6Width Tolerances of Hot-Rolled Strip(Carbon andHigh-Strength,Low-Alloy Steel)(Coils and Cut Lengths,Including Pickled) Specified Width,in.Width Tolerance,Over andUnder,in.Over ThroughMill Edgeand SquareEdge StripCut EdgeThrough0.109in.Over 0.109in.

Edge)N OTE 1—Camber is the deviation of a side edge from a straight line.The standard for measuring this deviation is based on any 8-ft length.B It is obtained by placing an 8-ft straightedge on the concave side and measuring the maximum distance between the strip edge and the straight-edge.For strip wider than 11⁄2in.—1⁄4in.in any 8ft.For strip 11⁄2in.and narrower—1⁄2in.in any 8ft.AWhen the camber tolerances shown in the above table are not suitable for a particular purpose,hot-rolled strip is sometimes machine straightened.BFor strip less than 8ft tolerances are to be established in each instance.A formula for calculating camber is as follows:L 23C 1645C 2in L where:C 1=Camber in 8ft andC 2=Camber in any given length L .TABLE9Flatness Tolerances of Hot-Rolled Strip(Carbon and High-Strength Low-Alloy)It has not been practicable to formulate flatness tolerances for hot-rolled carbon strip steel because of the wide range of widths and thicknesses,and variety of chemical compositions,mechanical properties and types,produced in coils and cut lengths.16.Packaging16.1Unless otherwise specified,the strip shall be packaged and loaded in accordance with Practices A 700.16.2When specified in the contract or order,and for direct procurement by or direct shipment to the government,when Level A is specified,preservation,packaging,and packing shall be in accordance with the Level A requirements of MIL-STD-163.16.3When coils are ordered it is customary to specify a minimum or range of inside diameter,maximum outside diameter,and a maximum coil weight,if required.The ability of manufacturers to meet the maximum coil weights depends upon individual mill equipment.When required,minimum coil weights are subject to negotiation.17.Keywords17.1carbon;steel;stripANNEX(Mandatory Information)A1.PERMISSIBLE V ARIATIONS IN DIMENSIONS AND MASS IN SI UNITSA1.1Listed in Tables A1.1-A1.7are permissible varia-tions in
