Historical Version s – view previous versions of standard. BIf chromium and silicon contents are each a8847. With the additional elements such as those noted above, the added strength of the steel itself allows for a lighter wall thickness of steel to be used than for carbon steel ashm in order to meet structural physical requirements.

Chemical composition Grade Mfg. Outside dimension tolerances for square and rectangular tubing shall not exceed the specified plus and minus tolerances. The values stated in satm system may not be exact equivalents; therefore, each system shall be used independently of the other. Tubing having other dimensions may be furnished provided such tubing complies with all other requirements of this specification.

Combining values from the two systems may result in non-conformance with the standard. Twist tolerances for square and rectangular structural tubing shall be indicated.

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.

NOTE 2-For methods of estimating the atmospheric corrosion resistance fo low alloy steels see Guide G or actual data.

According to ASTM A, the weld seam location for square, rectangle and other special shaped tubing shall not be located within the corner radius unless specified by the customer or manufacturer. AApplies to specified wall thicknesses 0. NOTE 1-Products manufactured to this specification may not be suitable for those applications atsm low temperature notch toughness properties may be important, such as dynamically loaded elements in welded stuctures, etc.

The atmospheric corrosion resistance of this steel in most envi-ronments aastm substantially better than carbon steel with or without copper addition Note 2. This abstract is a brief summary of the referenced standard. For lighter wall thicknesses, elongation will be by agreement. ABecause of the degree to which phosphorus segregates, roduct analysis for this element is not technologically appropriate for rephosphorized steels unless misapplication is clearly indicated.

Under ASTM A, the corner radius for square and rectangular tubing shall not exceed three times the corner radius. As a standard under ASTM A, electric resistance welded tubing is normally provided without removal of inside flash.
