AM-355 stainless steel is a martensitic stainless alloy (13% Cr, 4.7% Ni, 2.7% Mo) used in aerospace applications requiring high strength and corrosion resistance at elevated temperatures. The T850 temper (solution heat-treated and age-hardened) provides yield strengths in the 1380–1520 MPa range with good bearing strength and moderate ductility, suitable for critical fasteners, compressor components, and high-stress structural applications to approximately 315°C.
