Historical Version s – view previous versions of standard. This specification covers standard requirements for cold-formed welded and seamless high-strength, low-alloy round, square, rectangular, or special shaped structural tubing for welded, riveted, or bolted construction of bridges and buildings and for general structural purposes where high strength and enhanced atmospheric corrosion resistance are required.

Round and shaped tubing shall meet the required tensile properties such as tensile strength, yield strength, and elongation. Heat and s847 analysis shall be performed wherein steel materials shall conform to the required chemical composition for carbon, manganese, phosphorus, sulphur, and copper. Outside dimension tolerances for square and rectangular tubing shall not exceed the specified plus and minus tolerances.


Length tolerance for structural tubing shall be in accordance with the specified values. Twist wstm for square and rectangular structural tubing shall be indicated. 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. The atmospheric corrosion resistance of this steel in most environments is substantially better than carbon steel with or without copper addition Note 2.

When properly exposed to the atmosphere, this steel can be used bare unpainted for many applications. When this steel is used in welded construction, the welding procedure shall be suitable for the steel and the intended service. Tubing having other dimensions may be furnished provided such tubing complies with all other requirements of this specification.


Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

Combining values from the two systems may result in non-conformance with the standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Note 1 — Products manufactured to this specification may not be suitable for those applications where low temperature notch toughness properties may be important, such as dynamically loaded elements in welded structures, etc.

Note 2 — For methods of estimating the atmospheric corrosion resistance of low alloy steels, see Guide G or actual data.
