This specification covers a corrosion and heat-resistant nickel alloy in the form of investment castings.
These castings have been used typically for structural parts requiring strength up to 1300 °F (704 °C) and oxidation resistance up to 1800 °F (982 °C), but usage is not limited to such applications.
Castings conforming to this specification are classified as follows:
Class 1Trace element limits conforming to AMS2280-1
Class 2Trace element limits conforming to AMS2280-2
Class 3Trace element limits do not apply
Castings shall conform to Class 3 unless Class 1 or Class 2 is specified by purchaser.
