17-4PH Stainless Steel H925
Verifiedmetal17-4PH Stainless Steel H925 is a precipitation-hardened martensitic stainless steel (17% Cr, 4% Ni, Cu, Nb) heat-treated to H925 condition (925°F/496°C aging) for high strength and corrosion resistance in aerospace applications including fasteners, shafts, and structural components. The H925 temper delivers approximately 1310 MPa (190 ksi) yield strength with moderate ductility and excellent fatigue resistance, suitable for service to approximately 300°C.

Quality & Standards
Industry-Specific
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
