17-7PH (17% Cr, 7% Ni, precipitation-hardening stainless steel) is a martensitic PH stainless used in aerospace and defense applications requiring high strength and corrosion resistance at elevated temperatures; the STA (solution-treated and aged) condition provides yield strengths in the 1200–1500 MPa range with good fatigue resistance and ductility suitable for springs, fasteners, and structural components operating to approximately 480°C.
