These are plain chromium stainless steels with varying chromium content between 12 and 18%, but with low carbon content.
Basic properties
- Moderate to good corrosion resistance increasing with chromium content
- Not hardenable by heat treatment and always used in the annealed condition magnetic
- Weldability is poor
- Formability not as good as the austenitics
Common uses
- Automotive trim (430)
- Automotive exhausts (409)
- Colliery equipment (3CR12)
- Hot water tanks (444)
