Form This specification covers a corrosion and heat-resistant steel in the form of bars@ wire@ forgings@ and forging stock. Application These products have been used typically for nuts and other parts requiring both corrosion and heat resistance up to 1500 ?F (816 ?C)@ but usage is not limited to such applications. At comparable elevated temperatures@ the strength of this steel is slightly higher than@ and the oxidation resistance is similar to@ 18Cr - 8Ni type steels. It is not recommended for use when welding is involved.
