17-4PH stainless steel H1075 is a precipitation-hardened martensitic stainless steel (17% Cr, 4% Ni, Cu, Nb) heat-treated to the H1075 condition, providing high strength (typically 1310 MPa yield) with moderate corrosion resistance suitable for aerospace fasteners, pump shafts, and turbine components operating to ~300°C. The H1075 temper offers a balance of tensile strength and fracture toughness through controlled precipitation hardening, with applications spanning military and commercial aircraft engines and hydraulic systems per AMS 5604/5643 specifications.
