PH13-8Mo is a precipitation-hardening martensitic stainless steel (13% Cr, 8% Ni, Mo) used in aerospace and high-performance applications requiring high strength (yield strength typically 1,240–1,520 MPa depending on temper) and good corrosion resistance up to ~300°C. The H-series tempers (H950–H1150) provide increasing strength levels through controlled aging, with H1050 being the most common aerospace specification balancing strength and fracture toughness.
