PH13-8Mo H1100 is a precipitation-hardened martensitic stainless steel (13% Cr, 8% Mo, 2.5% Ni) that achieves high strength (typically 1310 MPa yield) through H1100 heat treatment (1100°F aging), providing excellent corrosion resistance and fatigue performance for aerospace fasteners, landing gear components, and other critical applications requiring high strength-to-weight ratio at elevated temperatures up to ~315°C. Available in forged, ring, and extruded bar forms, this alloy offers good ductility and toughness balanced with superior tensile strength suitable for demanding structural and fastening applications per AMS 5629.
