Summary
Compared with 410, martensitic stainless steel is low-carbon; it has excellent bendability and function of the welding part.
Features
1) Good weldability;
2) Good bending performance;
3) Hardening occurs after heat treatment;
4) Magnetic;
5) Not suitable for harsh corrosive environment.
Scope of application
Refrigerated container structure and outer materials, automobile exhaust pipes, heat-resistant equipment parts.
