This is a precipitation-hardened martensitic stainless steel combining 11% chromium and 10% nickel with molybdenum and aluminum additions, designed to achieve high strength while maintaining corrosion resistance and toughness. It is used in demanding aerospace and industrial applications where both corrosive environments and high mechanical loads must be withstood, such as landing gear, fasteners, and hydraulic components. The aluminum content enables age-hardening to achieve exceptional strength levels while the nickel and molybdenum additions preserve ductility and resistance to stress-corrosion cracking compared to conventional martensitic stainless steels.
