15-5PH is a precipitation-hardened martensitic stainless steel (15% Cr, 5% Ni, 3% Cu) designed for high-strength aerospace and mechanical applications requiring excellent corrosion resistance and fatigue performance up to approximately 550°C. The H1025 condition provides maximum hardness and strength through precipitation hardening, typically yielding tensile strengths in the 1310–1380 MPa range with good toughness relative to other high-strength stainless alloys.
