高压双头螺栓a193b7/a1942h什么材质
提问者采纳
是美标螺栓材料，A193 Gr B7螺栓化学成分和机械性能要符合A193 Gr B7标准要求，A194 Gr 2H螺母化学成分和机械性能要符合A194 Gr 2H螺母标准要求。这种组合的螺栓在国内是可以买到的。这是螺栓材料，我公司一般用35CrMoA/30CrMo代。这是得到北京设计院认可的，在中石化范围内普遍使用这个规则。

美标A193 Gr B7螺栓和A194 Gr 2H螺母可以用中国的什么材质替代？
美标A193 Gr B7螺栓和A194 Gr 2H螺母，可以用中国的什么材质替代？两者之间有什么区别？强度等级又应该选用中国标准中的哪一种？求知道的大神讲解。

这是美标，A193 Gr B7螺栓化学成分和机械性能要符合A193 Gr B7标准要求，A194 Gr 2H螺母化学成分和机械性能要符合A194 Gr 2H螺母标准要求。A194 Gr 2H螺母材质可以用45#钢做。A193 Gr B7螺栓材质就买B7材料，B7材料国内能买到。强度等级一定要用美标的，国内没有标准可以代替。具体可以参见美国紧固件标准大全IFI英制紧固件标准手册第八版，IFI英制紧固件标准手册第八版可以找我购买。
