This specification covers a corrosion and heat resistant nickel alloy in the form of bars, forgings, extrusions, flash welded rings, and stock for forging or flash welded rings. These products have been used for parts requiring both corrosion and oxidation resistance up to 2000 degrees F (1093 degrees C) and where such parts may require welding during fabrication, but usage is not limited to such applications.
