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 subjected to welding, brazing, or other exposure at temperatures over 800 °F (427 °C) during fabrication, but usage is not limited to such applications. Also has been used for parts requiring oxidation resistance up to 1500 °F (816 °C) but useful at that temperature only when stresses are low.
