17-4PH H1150 is a precipitation-hardened martensitic stainless steel (17% Cr, 4% Ni, Cu-strengthened) designed for high-strength aerospace and defense applications requiring corrosion resistance up to ~300°C. The H1150 condition (solution-treated and aged at 1150°F) provides ultrahigh yield strength (typically 1310 MPa) with moderate elongation, making it suitable for critical fasteners, shafts, and structural components in gas turbines and aircraft engines.
