PH13-8Mo is a precipitation-hardening martensitic stainless steel (13% Cr, 8% Ni, 2.5% Mo) used in aerospace applications requiring high strength (typically 1300+ MPa yield) combined with moderate corrosion resistance and good fatigue properties; the H1150 condition provides optimal strength through heat treatment at 1150°F with excellent dimensional stability for critical fasteners and structural components.
