By optimizing chemical composition ratio and controlling w(C)+w(N), w(Cr)eq, w(Ni)eq and equivalence ratio, improved the cold working stability of metastable austenite stainless steel. By studying the relation between strength, plasticity, hardness, crystal degree and solid solution treatment process, the appropriate solid solution treatment process was determined as 1150 ℃×2 min. It solved the problems that work-hardening tendency for economical metastable austenite stainless steel is severe and forming property has a poor performance.
