  2. 1. The role of alloy element in martensitic stainless steel CA6NMCr

Cr is a typical ferrite formation element. Excessive Cr can promote δ ferrite formation. Therefore after solution treatment it will not get full martensite. There is part of delta ferrite. Thereby it’ll affect the steel toughness and stress corrosion resistance. Therefore, the Cr content of super martensitic stainless steel should be strictly controlled between 12% and 13%.
