Form:

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

Application:

This tubing has been used typically for parts, such as fluid lines, subject to medium high pressures and requiring corrosion resistance, but usage is not limited to such applications. Welding, brazing, or other exposure to temperatures over 800 °F (427 °C) during fabrication may impair corrosion resistance.

Classification:

The tubing covered by this specification is classified as follows:

Type 1 - Seamless

Type 2 - Welded and drawn

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