PH13-8Mo stainless steel is a precipitation-hardening martensitic stainless steel containing molybdenum and copper that delivers high strength (typically 1,310 MPa yield) with good corrosion resistance, suited for aircraft engine components and fasteners. The H950 condition is aged to provide peak hardness and tensile properties while maintaining adequate ductility and fracture toughness for critical aerospace applications per AMS 5629.
