本帖最后由 zhaoqingsheng 于 2019-10-3 10:36 编辑 想知道不锈钢牌号“022Cr17Ni12Mo2”中的开头数字“022”是啥意思?请师傅们指点!!

请问:含碳量0.03%,为什么表示为022?什么含义?
Reply #32019-10-03
含碳量是个范围,就像Cr17,Cr的含量在16.0-18.0范围
Reply #42019-10-03
另外,旧牌号00Cr17Ni14Mo2比较好理解。旧牌号中的Ni14,为什么变成了Ni12?

022数字代码这里相当于碳含量小于等于0.03%。GBT 20878 起草编码细节谁说一下?谢谢
Reply #92019-10-04
022就是说的碳含量,至于为什么要用022是不是说碳含量在这个数值时候是最优性能,一般来说牌号标注的成分含量在实际生产中都是有一定的范围的

022代表超低碳的意思,为什么非要用022得问标准制定人了
