Alloy 422 Stainless Steel Bar - AMS 5655
Alloy 422 stainless bar is a hardenable, martensitic stainless steel designed for service temperatures as high as 1200 F. This grade develops high mechanical properties via heat treatment and offers good scaling and oxidation resistance. Typical applications have included buckets and blades in steam turbines, high temperature bolting and valve and valve trim.
