410S
Alloy 410S is a low carbon, non–hardening modification of Alloy 410 the general purpose 12% chromium martensitic stainless steel. The low carbon and a small alloy addition minimize austenite formation at high temperatures which restricts the alloys ability to harden.

Properties & Typical Applications
410S remains soft and ductile even when rapidly cooled from above the critical temperature. This non-hardening characteristic helps prevent cracking when the alloy is exposed to high temperatures or welded.Typical applications include petroleum refining, petrochemical processing,thermal processing , gate valves,press plates , heat exchangers,ore processing and mining machinery.
