阀门材料及标准

547（一）材料可以有好多种，45K，60K，75K主要指的是屈服强度，不同的热处理调制，会得到不同的强度。材料可以是一样的。4130是主要材料。（二）ENP（Electroless Nickel plating）工艺是一种用非电镀（化学）的方法，在零部件表面沉镀出十分均匀、光亮、坚硬的镍磷硼合金镀层的先进表面处理工艺。

（三）A105是美国ASTM标准号，A代表的是普通碳素结构钢。标准名：管道部件用碳素钢锻件。因为这个标准里只规定了一种碳钢锻件，A105也就算一种锻件碳钢牌号。A105也是一种材质代号,属于特殊钢材，是一种冷锻钢。A105是一种低碳钢锻件，与20钢类似。

（四）不锈钢螺丝A193/B7

A193是美国材料学会的一个标准号，B7是该标准中的一个材料的代号，该标准中规定了B7材料的化学组成成分的范围，但没有指定相应的牌号，你可以根据该标准的要求去找国内满足条件的相关材料牌号。

（五）突面raised face (RF)

全平面flat face; full face (FF)

凹面female face (FMF)；凸面male face (MF)；凹凸面（MFM）

榫槽面（TG）

环垫接头ring joint (RJ)

对焊butt welded (BW)

承插焊socket welded (SW)

美国标准锥管螺纹American standard taper pipe thread (NPT)

这些都是连接方式表示方法：

RF＝大突面法兰连接

RTJ＝环形垫法兰连接

SW＝承插焊连接
