6、e Year Review and update of this specification. 1. SCOPE 1.1 Form This specification covers a corrosion and heat-resistant steel in the form of seamless tubing. 1.2 Application This tubing has been used typically for parts requiring both corrosion and heat resistance, especially when such parts are

7、welded during fabrication, but usage is not limited to such applications. Also for parts requiring oxidation resistance up to 1500 F (816 C), but useful at that temperature only when stresses are low. 2. APPLICABLE DOCUMENTS The issue of the following documents in effect on the date of the purchase

8、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 published issu
