Review Annealing of Cold-worked Austenitic Stainless Steels
Austenitic stainless steels (ASSs) usually exhibit ex-cellent corrosion resistance, toughness and weldability. However, the strength level, particularly the yield strength, is relatively low, about 200MPa, in the annealed state. In order to increase their strength, ASSs are often cold work-ed after solution annealing. Cold work is a convenient
