PH13-8Mo is a martensitic precipitation-hardening stainless steel (13% Cr, 8% Mo) that achieves high strength through aging heat treatment, offering excellent corrosion resistance and fatigue performance in aerospace and defense applications up to approximately 480°C. The H1025 condition (solution-treated and aged) provides tensile strength around 1310 MPa with good ductility and toughness, suitable for highly stressed structural components including fasteners, landing gear, and pressure vessels.
