Form:

This specification covers a corrosion and heat resistant steel in the form of bars, wire, forgings, mechanical tubing, flash welded rings, and stock for forging, flash welded rings, or heading.

Application:

These products have been used typically for formed parts requiring oxidation resistance up to 1000 °F (538 °C), but usage is not limited to such applications. Strength at the higher temperature is superior to that of the standard 12Cr type steel.
