Form:

This specification covers a corrosion and heat resistant steel in the form of welded tubing.

Application:

This tubing has been used typically for parts requiring both corrosion and heat resistance, especially when such parts are welded during fabrication, and for parts requiring oxidation resistance up to 2000 °F (1093 °C) though useful at that temperature only when stresses are low, but usage is not limited to such applications.
