Scope

This specification covers a corrosion and heat resistant iron-chromium-nickel-cobalt alloy in the form of bars, wire, forgings, flash welded rings, and stock for forging, flash welded rings, or heading. These products have been used typically for parts, such as turbine rotors, shafts, blades, and bolts, requiring high strength up to 1350 degrees F (732 degrees C) and oxidation resistance up to 1800 degrees F (982 degrees C), but usage is not limited to such applications.
