SCOPE 1.1 Form This specific
6、ation covers a corrosion and heat resistant steel in the form of seamless tubing. 1.2 ApplicationThis tubing has been used typically for parts, such as fluid-conducting lines, requiring both corrosion and heat resistance, especially when such parts are welded or brazed during fabrication, and which
7、require strength higher than that of the 18 8 type steels, or require oxidation resistance up to 1100 F (593 C), but usage is not limited to such applications. 2. APPLICABLE DOCUMENTS The issue of the following documents in effect on the date of the purchase order forms a part of this specification
8、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 published issue of that document shall apply. 2.1 SAE P
