Full Description

This specification covers a corrosion and heat resistant nickel-iron 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, such as turbine discs, shafts, and blades, requiring high strength than AMS 5660 up to 1400 degrees F (760 degrees C) and oxidation resistance up to 1600 degrees F (871 degrees C), but usage is not limited to such applications.
