Form:

This specification covers a corrosion and heat-resistant steel in the form of seamless 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 also for parts requiring oxidation resistance up to 1500 °F (816 °C), but useful at that temperature only when stresses are low, but usage is not limited to such applications.
