15-5PH H925 is a precipitation-hardened martensitic stainless steel (15% Cr, 5% Ni) in the H925 condition—solution heat-treated, cold-worked, and aged at 925°F—providing yield strength of approximately 170 ksi with good corrosion resistance and fracture toughness for aerospace fasteners and structural components operating to moderate temperatures. This condition balances high strength with ductility suitable for applications requiring reliable fatigue performance in saltwater and mildly corrosive environments.
