301 Stainless Steel｜Foshan Huili Metal Technology Co., Ltd.（佛山市惠利金属科技有限公司）
Hardness and strength rise sharply after cold work with a very high work-hardening rate — one of the few austenitics that gets much harder when pressed — but corrosion resistance is a bit below 304.

Performance
Hardness and strength rise sharply after cold work with a very high work-hardening rate — one of the few austenitics that gets much harder when pressed — but corrosion resistance is a bit below 304.
Use cases
Springs, spring strips, rail-vehicle structures, phone shielding parts and high-strength thin strip; strengthening comes from deformation, not chemistry.
Characteristics
Can be hardened to very high strength (1/2H, 3/4H, H tempers); ductility and formability drop as hardness increases.
