Designated as UNS N06601 or W.Nr. 2.4851, Inconel 601 (also called “Alloy 601”) is a nickel-chromium-iron alloy with an addition of aluminum for outstanding resistance to oxidation, and other forms of high-temperature corrosion as well as improved nitriding resistance. It also has high mechanical properties at elevated temperatures. Inconel 601 may be used for industrial furnaces, heat-treating equipment such as baskets, muffles, and retorts, strand-annealing tubes, petrochemical and other process equipment, burner nozzles, gas turbine equipment, superheater tube supports & grid barriers of power plant piping, etc.
