Grade Overview

Introduction & Overview — SS 439 Coils / AISI 439 Coils

SS 439 Coils / AISI 439 Coils are ferritic stainless steel coils stabilized with titanium, offering excellent resistance to corrosion, oxidation, and stress corrosion cracking. This grade contains low carbon content, which improves weldability and prevents intergranular corrosion. The addition of titanium stabilizes carbon and nitrogen, preventing carbide precipitation during welding or high-temperature exposure.
