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, such as shrouds, ducts, and cases, requiring oxidation resistance up to 1000 °F (538 °C), but usage is not limited to such applications. Creep strength and resistance to tempering of this steel are better than those of the common 13Cr type.
