Custom 450 is a martensitic stainless steel precipitation-hardened to the H900 condition, delivering very high strength (typically 1450+ MPa yield) with good corrosion resistance and fatigue performance for aerospace bearing and structural applications. The H900 temper provides optimized strength-toughness balance through controlled heat treatment, suitable for highly-stressed rotating components and fasteners per AMS 5763/5773 specifications.
