Custom 450 stainless steel is a martensitic stainless steel (chromium-based with controlled carbon and molybdenum additions) used primarily in aerospace applications requiring high strength and corrosion resistance at elevated temperatures. The H1150 condition is a hardened and tempered state providing ultimate tensile strength approximately 1,150 ksi (7,930 MPa) with moderate ductility, suitable for critical fasteners and structural components in gas turbine engines and high-performance aircraft systems.
