PH13-8Mo is a precipitation-hardening martensitic stainless steel (13% Cr, 8% Ni, 2.4% Mo, 1.1% Al) used in aerospace fasteners, springs, and airframe components requiring high strength (yield strengths 1240–1380 MPa) combined with moderate corrosion resistance and cryogenic toughness; the "sta" condition denotes stress-relieved and aged hardening for optimal mechanical properties and dimensional stability.
