Expert Answer:

The properties necessary in metallic materials intended for service at high temperatures are outlined and the characteristics of nickel-base alloys for such applications are particularly described. The materials are dealt with in two classes: those primarily of value because of their resistance to oxidation and those characterized by high strength at elevated temperatures. Thus alloys are better suited for use as electrical heating devices.
