RATIONALE

AMS5854C revises Condition (3.3.2), Properties (3.5.1.2.3) and Reports (4.4), and is a Five Year Review and update of

this specification.

1. SCOPE

1.1 Form

This specification covers a corrosion and heat-resistant nickel alloy in the form of bars, wire, forgings, flash welded rings,

and extrusions 4 inches (102 mm) and under in nominal diameter or least distance between parallel sides, and stock for

forging or flash welded rings.

1.2 Application

These products have been used typically for parts requiring both corrosion and oxidation resistance up to 1,000 °F (538 °C),

and where such parts may require welding during fabrication and are then precipitation heat treated to develop required

properties, but usage is not limited to such applications.

2. APPLICABLE DOCUMENTS

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 cancelled and no superseding document has been specified, the last

published issue of that document shall apply.
