CRS1018钢是什么钢？用国内哪种钢材替代

CRS 1018 是美国的一种低碳钢的型号，18指的是他的含碳量~~是万分子几表示的平均值 。是美国机动工程师协会标准代号（SAE），推荐国内可以用20钢代用。。

冷轧钢COLD ROLL STEEL
RS:COLD ROLLED STEEL冷轧板的统称，在冲压材料上指SPCC（表示一般用冷轧碳素钢薄板及钢带,相当于中国Q1九5-2一5A牌号）
1018是美国材料,他的含锰量比较高,和国内的16Mn或者15Mn,20Mn化学组成类似,和20号钢和Q235的含碳差不多,但是含锰量就差很多了.10代表碳锰钢 18代表碳含量. 硬度:50硬度,未热处理,≤197HB,热处理规范,正火,910℃.
1018化学成份(%): C :0.17～0.24 Mn :0.70～1.00 P :≤0.035 S :≤0.035 Si :0.17～0.37 Cr :≤0.25 Cu :≤0.25 Ni :≤0.25
