This specification covers a corrosion and heat resistant nickel alloy in the form of bars, forgings, flash welded rings, and stock for forging or flash welded rings.

These products have been used typically for parts requiring both corrosion and oxidation resistance and where such parts may require welding during fabrication and for parts requiring oxidation resistance up to 2000 degrees F (1093 degrees C) but useful at the higher temperatures only when stresses are low, but usage is not limited to such applications. Strength at elevated temperatures is similar to that of the 18-8 type of steel.
