ENDURO AA is a ductile, non-hardening alloy containing 14 to 18 percent chromium with carbon under 0.12 per cent. It has mechanical properties equal to high grade medium carbon steel, with high resistance to general corrosion and oxidation at high temperatures. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness, creep, and fatigue. It also includes information on low and high temperature performance, and corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: SS-9.
