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, such as fluid-conducting lines, requiring both corrosion and heat resistance, especially when such parts are welded or brazed during fabrication, and which require strength higher than that of the 18 8 type steels, or require oxidation resistance up to 1100 °F (593 °C), but usage is not limited to such applications.
