SCOPE1.1 FormThis specification covers a corrosion and heat resistant
6、steel in the form of bars, wire, forgings, and forging stock.1.2 ApplicationThese products have been used typically for parts, such as compressor blades and vanes, requiring oxidation resistance up to 1000 F (538 C), useful at the higher temperatures only when stresses are low, but usage is not limi
7、ted to such applications.2. APPLICABLE DOCUMENTSThe 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 specifi
8、ed. When the referenced document has been canceled and no superseding document has been specified, the last published issue of that document shall apply.2.1 SAE PublicationsAvailable from SAE, 400 Commonwealth Drive, Warrendale, PA 15096-0001 or www.sae.org.AMS 2241 Tolerances, Corrosion and Heat Re
