This specification covers three grades of seam-welded, round, tapered steel tubes for structural use.
Grades A and B are of low-carbon steel or high-strength low-alloy steel composition and Grade C is of weather-resistance steel composition. The tube steel shall be hot-rolled aluminum-semikilled or fine-grained killed sheet or plate manufactured by one or more of the following processes: The tubes shall be made from trapezoidal sheet or plate that is preformed and then seam welded.
Xstm shall be brought to final size and properties by roll compressing cold on a hardened mandrel. A tensile test shall be done to determine the yield strength and the ultimate tensile strength of the tubes.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. Grades A and B are of low-carbon steel or high-strength axtm steel composition and Grade C is of weather-resistant steel composition. Wall thicknesses range from 0.
Tapers are subject to agreement with the manufacturer. The values stated in each system may not be exact equivalents; therefore, each system shall be used indepedently of the other.
Combining values from the two systems may result in non-conformance with the standard.
