SAEJ403SAE碳钢化学成分
SAEJ403SAE碳钢化学成分SAE碳钢化学成分SAE J403 （2001年11⽉修订）1. 范围1941年，SAE 钢铁部与美国钢铁协会合作在表达SAE钢铁成分范围⽅⾯发⽣了很⼤的变化。
现在所实⾏的计划是基于铸造或热⼒分析以及样件的产品特性分析，⽽不是SAE钢中的碳及其他元素制造的⽆公差限制的产品。
在钢铁业中铁的化学成分已是⼀个众所关⼼的问题。
铁的等级提⾼了运送的效率是⼤家都承认的，且此次为科技创新，提⾼产品质量⽅⾯提供给了⼀个机会，因此，为这些等级的产品提供了更多应⽤的可能性。
完整且公正的研究决定着最需要的规定的等级，且成分的可⾏性也有如此要求。
选出钢中最常⽤等级的钢并保存在修订版中。
表1,2,3A和3B已给出铸造或热化学成分限制等级。
SAE J409已给出产品分析中铸造或热⼒限制要求。
因为AISI不再指明铁的等级名称，⽂件中所列等级即为SAE等级。
众所周知需要的是化学成分，⽽不是表中所提到的其他⽅⾯。
如要求该种铁，可通过以下三种⽅式获得所规定的化学成分：a)通过最⼩限制b)通过最⼤限制c)通过最⼤和最⼩限制其范围。
表4给出了碳钢的不同元素的铸造或热⼒分析。
该表给出了最⼤限度和最低限度间的范围（即：0.06范围是0.19-0.25）。
SAE J409给出了不同标准产品的铸造或热⼒限制。
ISTC 部门1开发了⼀个程序，该程序允许维持⽂件中所列等级。
这包括对全⾏业的调查。
技术协会将进⾏该项调查。
该项标准的出台是对其的补充或是在等级列表中除去某些等级。
基于让等级满⾜SAE等级的标注及化学成分，新等级应满⾜以下条件：⾄少⽣产或消耗225吨/年，且⾄少有2个⽤户或⽣产商赞助。
基于SAE J1081中的准则，新的铁成分将被视为新标准的铁，直⾄新的⽣产铁达到⽣产⽔平或使⽤⽔平，并作为标准铁。
基于等级调查，等级的删除应得到⼤家的⼀致同意。
且删除等级应在SAE J1249中存档。
当要求说明铸造或热⼒分析以说明与表1,2,3A或3B的化学限制相符时，除了说明碳，镁，磷，硫的含量，也得说明铜，铬，镍，钼及硅元素的含量。

Brinell hardness shall be determined according to ASTM E 10,Standard Test Method for Brinell Hardness of Metallic Materials, after sufficient material has been removed from the casting surface to insure representative hardness readings. The 10mm tungsten ball and 3000kg load shall be used unless otherwise agreed upon.5.Heat Treatment5.1The heat treatment of castings and test specimens produced to this standard in order to meethardness or other mechanical property requirements, for thermal stress relief or for other purposes is permissible only with the express approval of the casting purchaser.5.2Purchaser approval may be blanket or may be issued on a case-by-case basis, as agreed.5.3Unless otherwise agreed, the heat treat cycles employed; times, temperatures, rates, quenchants,etc. shall be at the option of the manufacturer.5.4Unless otherwise agreed, any separately cast test specimens or any removed from the castings,must accompany the castings they represent as part of the same heat treatment lot(s) or besubjected to the same thermal cycle as the castings they represent, in all respects.6.MicrostructureThe graphite component of the microstructure shall consist of at least 80% spheroidal graphite conforming to Types I and II (per ASTM A247) in Fig. 1 (nodularity rating chart developed by the Ductile I ron Society may be used as a guide). The matrix microstructure shall consist of ferrite, ferrite and pearlite, pearlite, tempered pearlite, or tempered martensite, or a combination of these. The microstructure shall be substantially free of primary cementite. The microstructure shall be substantially free of undesirable carbides, the details of which are agreed upon between the casting manufacturer and the purchaser. Examples of matrix microstructures for each grade are shown in Fig. 2.FIGURE 1—CLASSIFICATION OF GRAPHITE SHAPE IN CAST IRONS (FROM ASTM A 247)D400D450FIGURE 2—TYPICAL MATRIX MICROSTRUCTURES(PHOTOS COURTESY OF CLIMAX RESEARCH SERVICES)D500D550FIGURE 2—TYPICAL MATRIX MICROSTRUCTURES (CONTINUED)(PHOTOS COURTESY OF CLIMAX RESEARCH SERVICES)D700D800FIGURE 2—TYPICAL MATRIX MICROSTRUCTURES (CONTINUED)(PHOTOS COURTESY OF CLIMAX RESEARCH SERVICES)7.Quality AssuranceIt is the responsibility of the manufacturer to demonstrate process capability. The specimen(s) used to do so shall be of a configuration and from a location agreed upon between the manufacturer and the purchaser. Sampling plans shall be agreed upon between the manufacturer and purchaser. The manufacturer shall employ adequate controls to ensure that the parts conform to the agreed upon requirements.8.General8.1Castings furnished to this standard shall be representative of good foundry practice and shallconform to dimensions and tolerances specified on the casting drawing.8.2Minor imperfections usually not associated with the structural functioning may occur in castings.These imperfections are often repairable; however, repairs should be made only in areas and by methods approved by the purchaser.8.3Purchaser and manufacturer may agree to additional casting requirements, such as manufactureridentification, other casting information, and special testing. These should appear as additionalproduct requirements on the casting drawing.9.Notes9.1Marginal IndiciaThe change bar (l) located in the left margin is for the convenience of the user in locating areas where technical revisions have been made to the previous issue of the report. An (R) symbol to the left of the document title indicates a complete revision of the report.PREPARED BY THE SAE AUTOMOTIVE IRON & STEEL CASTINGS COMMITTEEA.3.5Typical microstructures of the grades of ductile iron are as follows:D400 (D4018) is a ferritic ductile iron most commonly made by annealing. The annealing time and temperature cycle is such that primary carbides, if present in the as-cast structure, are decomposed, and the resulting matrix is ferritic.D450 (D4512) is ferritic ductile iron supplied either as-cast or heat-treated. The matrix, is predominantly ferrite, but this grade can contain pearlite, depending on section size.D500 (D5006) is ferritic-pearlite ductile iron supplied either as-cast or heat-treated. The matrix, is essentially pearlite. This grade may contain substantially more ferrite than Grade D550.D550 (D5504) is pearlitic-ferritic ductile iron supplied either as-cast or heat-treated. The matrix, is essentially pearlite. This grade may contain less ferrite than D500.D700 (D7003) is either as-cast or air quenched to a specified hardness range. The resulting matrix is pearlite.D800 is either as-cast or air or liquid quenched and tempered to a specified hardness range.The resulting matrix is pearlite or tempered martensite.DQ&T is a liquid quenched and tempered grade. The resulting matrix is tempered martensite.A.4C asting Mechanical PropertiesA.4.1The mechanical properties are shown in Table 1. Since properties may vary with location in agiven c asting, the suitability of a particular grade for an intended use is best determined bylaboratory or service t ests.A.4.2The mechanical properties will vary with microstructure that, especially in the as-cast condition, isdependent upon section size as well as chemical composition and some foundry processes.A.4.3For optimum mechanical properties in the quenched and tempered grade, section size forunalloyed iron should generally not exceed 19mm (3/4 inch) to insure uniform, thoroughhardened structure.A.4.4 A young's Modulus value of 166GPa (24Mpsi) is typically found for ductile iron when measuredper ASTM E111, Standard Test Method for Young's Modulus, Tangent Modulus and ChordModulus. Ductile Iron components used for high strain rate applications should use a reducedvalue of the modulus stated above (some designers have used up to 15% less than the modulus stated above).A.4.5T ypical un-notched Charpy impact energy properties are shown in Table A2. These typicalresults are from low residual element content iron (especially phosphorus). Impact values areaffected by microstructure and section size.- 11 -RationaleNot Applicable.Relationship of SAE Standard to ISO StandardNot Applicable.ApplicationThis SAE standard covers the minimum mechanical properties measured on separately cast test pieces of varying thickness and microstructural requirements for ductile iron castings used in automotive and allied industries. Castings may be specified in the as-cast or heat-treated condition. If castings are heat-treated, prior approval from the customer is required.The appendix provides general information on chemical composition, microstructure and casting mechanical properties, as well as other information for particular service conditions.In this standard SI units are primary and in-lb units are derived.Reference SectionASTM E10—Standard Test Method for Brinell Hardness of Metallic MaterialsASTM E23—Standard Test Methods for Notched Bar Impact Testing of Metallic MaterialsASTM E111—Standard Test Method for Young's Modulus, Tangent Modulus and Chord ModulusASTM A247—Standard Test Method for Evaluation the Microstructure of Graphite in Iron CastingsASTM A536—Standard Specification for Ductile Iron CastingsSTP-455—Gray, Ductile, and Malleable Iron Castings Current Capabilities (out-of-print)Metals Handbook, Vol. 1,2 and 5, 8th Edition, ASM International, Materials Park, OH (out-of-print)Gray and Ductile Iron Castings Handbook, Gray and Ductile Iron Founder's Society, Cleveland, OHH.D.
