SCOPE 1.1 Form This specification covers a corrosion-resistant steel in the form of bars, wire, forgings, mechanical tubing, flash welded rings, and stock for forging or flash welded rings. 1.2 Application These products have been used typically for parts requiring corro
7、sion and heat resistance up to 800 F (427 C), but usage is not limited to such applications. Welding, brazing, or other exposure to temperatures over 800 F (427 C) during fabrication may impair corrosion resistance. 2. APPLICABLE DOCUMENTS The issue of the following documents in effect on the date o
8、f 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
