Custom 455 UNS S45500

This alloy is a martensitic stainless steel that combines corrosion resistance similar to 304, easy fabrication and one step age hardenability yielding strength characteristics similar to other martensitic stainless steels. It possesses a yield strength that is roughly 3 times the strength of standard 304 stainless. This alloy is extremely stable during heat treating so it can be machined to close tolerance prior to aging. It is widely used in applications where standard austenitic grades fail in terms of strength requirements in corrosive environments and martensitic grades fail in terms of corrosion resistance. It effectively brings together the best of both worlds.
