Form:

This specification covers a corrosion and heat resistant steel in the form of sand castings.

Application:

Primarily for parts requiring both corrosion and heat resistance up to 800°F (425°C), especially where such parts are welded during fabrication; for parts requiring oxidation resistance up to 1500°F (815°C) but useful at the higher temperatures only when stresses are low; and for parts requiring resistance to fuming nitric acid.
