422 Stainless Steels Applications and Specifications

These products have been used typically for parts requiring strength and oxidation resistance up to 1 000 °F (538 °C), but usage is not limited to such applications.

The issue of the following documents in effect on the date of the purchase order forms a part of this specification to the extent specified herein. The supplier may work to a subsequent revision of a document unless a specific document issue is specified. When the referenced document has been canceled and no superseding document has been specified, the last published issue of that document shall apply.

Alloy 422 is a hardenable stainless steel designed for use at temperatures of up to 1200ºF (649ºC). Alloy 422 has good resistance to scaling and oxidation. Through heat treatment, high mechanical properties can be developed. Alloy 422 is used in applications such as compressors or steam turbines and also in aircraft parts, valves, high temperature bolting etc.
