This specification covers a corrosion and heat resistant steel in the form of sheet, strip, and plate.

These products have been used typically for parts requiring both corrosion and heat resistance up to 1600 \mDF (871 \mDC), 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; SAE ARP 1110 recommends practices to minimize such conditions.
