Nickel Alloy, Corrosion and Heat Resistant, Bars, Forgings, and Rings 74Ni - 15.5Cr - 8.0Fe
|Publication Date:||1 December 2019|
This specification covers a corrosion and heat resistant nickel alloy in the form of round bars over 2.50 to 4.50 inches (over 63.5 to 114.3 mm), inclusive, in nominal diameter, forgings over 2.50 inches (63.5 mm) in nominal thickness, other bars and forgings, flash welded rings, and stock for forging or flash welded rings (see 8.6).
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 °F (1093 °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 steels.
