This specification covers a corrosion and heat resistant nickel alloy in the form of bars, forgings, flash welded rings, and stock for forging, flash welded rings. These products have been used typically for parts, such as fasteners, flanges, and rings, requiring high strength up to 1500 °F and oxidation resistance up to 1750 °F (954 °C), particularly those parts which are formed or welded and then heat treated to develop required properties, but usage is not limited to such applications.
