6、cification) and to insert minimum tensile strengths using values from ASTM A 249, and is a Five Year Review and update of this specification. 1. SCOPE 1.1 Form This specification covers a corrosion-resistant steel in the form of welded tubing. 1.2 Application This tubing has been used typically for
7、parts, such as fluid-conducting lines not subjected to high pressure, requiring good corrosion resistance, 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
8、 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 cance
9、lled and no superseding document 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.
