Description / Abstract:


This specification covers a corrosion and heat-resistant steel in the form of seamless or welded and drawn tubing.


This tubing has been used typically for parts requiring both corrosion and heat resistance, especially when such parts are welded during fabrication, but usage is not limited to such applications. The alloy provides oxidation resistance up to 1500 F (816 C) but is useful at that temperature only when stresses are low.


Tubing covered by this specification is classified as follows:

Type 1-Seamless

Type 2-Welded and drawn

Unless a specific type is ordered, either Type 1 or Type 2 may be supplied.
