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 to temperatures over 800 °F (427 °C) during fabrication, and also for parts requiring oxidation resistance up to 1500 °F (816 °C) but useful at that temperature only when stresses are low. Usage is not limited to such applications.
