AM-355 stainless steel is a precipitation-hardenable martensitic stainless steel (17% Cr, 4.3% Ni, 2.6% Mo) used in aerospace fasteners and structural components requiring high strength and corrosion resistance at elevated temperatures. The T1000 condition is aged to approximately 1000°F (538°C), providing ultimate tensile strengths in the range of 180–210 ksi with good fracture toughness and fatigue resistance for service to 600°F (316°C).
