Custom 450 stainless steel is a precipitation-hardened martensitic stainless steel (17% Cr, 4% Ni, 1% Mo) designed for high-strength aerospace applications requiring corrosion resistance and elevated temperature capability to approximately 600°F. The H1050 condition (solution heat-treated and aged) delivers tensile strength around 180 ksi with moderate ductility, suitable for bearing races, fasteners, and structural components in gas turbine engines and airframes per AMS 5763/5773 specifications.
