6、is specification. 1. SCOPE 1.1 Form This specification covers a corrosion-resistant steel in the form of bars, wire, forgings, extrusions, mechanical tubing, flash welded rings, and stock for forging, extruding, or flash welded rings. 1.2 Application These products have been used typically for parts
7、 requiring wear, galling, and corrosion resistance up to 950 F (510 C), but usage is not limited to such applications. Welding, brazing, or other exposure to temperatures over 950 F (510 C) during fabrication may impair corrosion resistance. 2. APPLICABLE DOCUMENTS The issue of the following documen
8、ts 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 ha
9、s 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.
