SCOPE1.1 FormThis specification covers a corrosion

6、and heat resistant steel in the form of seamless tubing.1.2 ApplicationThis tubing has been used typically for parts requiring both corrosion and heat resistance, especially when such parts are welded during fabrication and for parts requiring oxidation resistance up to 2000 F (1093 C) though useful

7、 at that temperature only when stresses are low, but usage is not limited 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 subsequ

8、ent 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 published issue of that document shall apply.2.1 SAE PublicationsAvailable from SAE International, 400 Commonwealth Drive
