加Cu，Mo等合金元素的铸造Cr－Mn－N系不锈钢在H2SO4，HNO3，HAC等不同介质中的抗磨蚀性能远优于304不锈钢，究其原因，除了Cr－Mn－N系不锈钢与304不锈钢有相似的耐蚀性能外，磨损实验证明其比Ni系不锈钢有更好的加工硬化能力，适用于磨损为主的工况.
The corrosive wear behavior of Cr-Mn-N casting stainless steel with addition of Cu and Mo in media of H2SO4, HNO3, HaC acid is investigated. Its corrosive wear resistance is much better than that of 304 stainless steel. and the reason is that, besides the similar corrosive resistance between Cr-Mn-N casting stainless steel and 304 stainless steel, the former has a better work-hardening ability than that of Ni series stainless steel in wear experiment. So it is fit for dominative wear condition.
