SCOPE 1.1 Form This specificat
6、ion covers a corrosion and heat-resistant steel in the form of sheet, strip, and plate. 1.2 Application These products have been used typically for parts requiring both corrosion and heat resistance, especially where such parts may require welding during fabrication, and for parts requiring oxidatio
7、n resistance up to 2000 F (1093 C) but useful at the higher temperatures only when stresses are very low, 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 to the
8、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 Publicat
