SCOPE 1.1 Form This specification covers a corrosion and heat resistant steel in the form of bars,
7、 wire, forgings, mechanical tubing, flash welded rings, and stock for forging or flash welded rings. 1.2 Application These products have been used typically for parts requiring corrosion and heat resistance and subject to very rigid inspection standards, especially when such parts are welded during
8、fabrication, for parts requiring oxidation resistance up to 1500 F (816 C) but useful at that temperature only when stresses are low, but usage is not limited to such applications. 2.
