Property requirements of super-martensitic stainless steel especially using for hydroelectric station are briefly introduced in this paper,characteristics and basic principle of alloying process of this steel,especially,the influence of alloy process on the content and distribution of retained austenite and δ ferrite in the steel are also analyzed in detail.

The concept of super austenitic stainless steel appeared with super ferrite stainless steel and super double phases stainless steel together.

The liquids of N08904 super austenitic stainless steel was computed and tested by means of theoretical calculation and thermal analysis,reasonable overheat was put forward and leaking problem of molten steel during continuous casting was solved and continuous casting production had come into effect.

The results showed that Cr20Ni18Mo6MnVSi super austenitic stainless steel in the chloride solution had excellent corrosion resistance properties after solution treatment at 1100℃ for 2h and followed by the aging treatment at 520℃ for 4h.
