The effect of total reduction ratio 12.5%~46.4% and solid solution treatment at 900~1150 ℃ on the structure and pmoperties of 3 mm sheet of a modifed type 202 metastable austenite stainless steel- 0.04C

15.21Cr
4.05Ni
1.65Cu
0.12N has been studied. The results showed that with 46.4% reduction cold rolling
about 26% deformation-induced a' martensite was formed and the tensile strength of the steel was up to 1200 MPa; the counter- transformation of a' martensite(a' to γ)occured by solid solution treatment
and with solid solution at 900 ℃ the a' mar- tensite was completely transformmed to γ austenite and the full recrystallization of stcel was finished; and the expected structure and excellent comprehensive mechanical properties were obtainad by solid solution treatment at 900~1100 ℃.
