430 Stainless Steel Sheet
430 stainless steel sheet is ideal for decorative and light industrial applications where moderate corrosion resistance and good formability are required.
Compared to 410 and 420, 430 offers better corrosion resistance and formability, while 410 and 420 provide higher hardness and strength for wear-resistant parts.
- Description
430 stainless steel sheet is a ferritic stainless steel containing chromium but no nickel.
It offers good corrosion resistance, excellent formability, and magnetic properties, making it a cost-effective alternative to austenitic grades for indoor and mildly corrosive environments.
