Type HE is an iron-chromium-nickel alloy with enough chromium to be suitable for service up to 2000 F and enough nickel to make it stronger and more ductile than the straight chromium stainless steels in the as-cast condition. As cast it has a two-phase, austenite-plus-ferrite structure containing carbides. At high temperatures ACI Type HE has excellent corrosion resistance, good ductility and moderate strength. It is used in the steel, power, oil refining and smelting industries. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness and creep. It also includes information on corrosion resistance as well as casting, heat treating, machining, and joining. Filing Code: SS-330. Producer or source: Stainless steel foundries.
