6、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 steel in the form of bars, wire, forgings, mechanical tubing, flash welded rings, and stock for forging, flash welded rings, or heading. 1.2 Applic
7、ation These products have been used typically for formed parts requiring oxidation resistance up to 1000 F (538 C), but usage is not limited to such applications. Strength at the higher temperature is superior to that of the standard 12Cr type steel. 2. APPLICABLE DOCUMENTS The issue of the followin
8、g 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 do
9、cument has been specified, the last published issue of that document shall apply. 2.1 SAE Publications Available from SAE International, 400 Commonwealth Drive, Warrendale, PA 15096-0001, Tel: 877-606-7323 (inside USA and Canada) or 724-776-4970 (outside USA), www.sae.org.
