5、uperseding AMS5560L Steel, Corrosion Resistant, Seamless Tubing 19Cr - 10Ni (SAE 30304) Solution Heat Treated (Composition similar to UNS S30400) RATIONALEAMS5560L results from a Five Year Review and update of this specification. 1. SCOPE 1.1 FormThis specification covers a corrosion-resistant steel
6、 in the form of seamless tubing. 1.2 ApplicationThis tubing has been used typically for parts, such as fluid-conducting lines, not subjected to high pressure and requiring good corrosion resistance, but usage is not limited to such applications. Welding, brazing, or other exposure to temperatures ov
7、er 800 F (427 C) during fabrication may impair corrosion resistance. 2. APPLICABLE DOCUMENTS 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 documen
8、t unless a specific document issue is specified. When the referenced document has been cancelled 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-
