15-5PH is a precipitation-hardening stainless steel (Fe-Cr-Ni-Cu-Nb) that combines moderate corrosion resistance with high strength and good fatigue properties, widely used in aerospace fasteners, springs, and structural components requiring performance to approximately 300°C. Available tempers range from H1025 (lowest strength) through H1150 (highest strength), with H900/H925/H935 providing intermediate strength levels optimized for specific applications balancing strength, toughness, and stress-corrosion cracking resistance.
