Form This specification covers a corrosion and heat-resistant steel in the form of sheet@ strip@ and plate. Application These products have been used typically for parts requiring both corrosion and heat resistance up to 1600 ??(871 ??@ but usage is not limited to such applications. At elevated temperatures@ strength of this steel is slightly higher than@ and oxidation resistance is similar to that of 18-8 type steels. Certain design and processing procedures may cause these products to become susceptible to stress-corrosion cracking; ARP1110 recommends practices to minimize such conditions.
