This specification covers a corrosion and heat resistant steel in the form of welded and drawn or seamless or drawn tubing. This tubing has been used typically for parts, such as fluid lines, subject to high pressures and requiring corrosion resistance, but usage is not limited to such applications. Tubing has good oxidation resistance up to 1100 °F (593 °C).
