Austenitic nickel-iron-chromium based superalloys are materials of choice for high temperature applications as they provide high temperature creep resistance associated with a suitable oxidation behavior in the temperature range of 600-1100°C. However, these properties are not sufficient for applications as Steam Methane Reformer (SMR). As a consequence, aluminum and chromium coatings are developed by the pack-cementation technique to improve their corrosion resistance. The oxidation behavior of the coated samples has been carried out in air at 1050°C. Chromium deposition leads to a layer of bcc chromium-iron solid solution. Oxidation tests indicated that a too high chromium concentration induces a too rapid growth of the chromia layer. In the case of aluminum coatings, a layer of -NiAl is formed at the surface of the alloy. It permits a significant decrease of the oxidation rate.

Abstract Type HU is an iron-chromium-nickel alloy containing about 60% alloying elements in the iron base. Its high chromium and nickel contents give this grade excellent resistance to corrosion by either oxidizing or reducing hot gases, particularly those containing appreciable amounts of sulfur. This excellent corrosion resistance and its excellent combination of high-temperature strength, resistance to thermal fatigue and resistance to carburization make this alloy especially suited for severe service conditions involving high stress and rapid thermal cycling. This datasheet provides information on composition, physical properties, hardness, and tensile properties as well as fracture toughness and creep. It also includes information on high temperature performance and corrosion resistance as well as casting, heat treating, machining, and joining. Filing Code: SS-374. Producer or source: Various stainless steel casting companies.
