Form

This specification covers a corrosion and heat resistant nickel alloy in the form of investment castings.

Application

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.

Classification

Castings conforming to this specification are classified as follows:

Class 1 Trace element limits conforming to AMS 2280-1

Class 2 Trace element limits conforming to AMS 2280-2

Class 3 Trace element limits do not apply

Castings shall conform to Class 3 unless Class 1 or Class 2 is specified by purchaser.
