For methods of estimating the atmospheric corrosion resistance of low alloy steels see Guide G or actual data. They can be considered to be microalloyed steel ast are designed for mechanical rather than compositional specs.

If the results of the mechanical tests representing any heat do not conform to a requirement, retests shall be made. This specification covers grades of hot-formed welded and seamless high-strength low-alloy square, rectangular, round, or special shape structural tubing for welded, riveted, or bolted construction of bridges and buildings and for general structural purposes.

Grade II has atmospheric corrosion resistance equivalent to that of carbon steel with copper 0. When properly exposed to the atmosphere, Grades Ia and Ib can be used bare unpainted for many applications. When enhanced corrosion resistance is desired, Grade III, copper limits may be specified. When enhanced corrosion resistance is desired, Grade III, copper limits may be specified.

This abstract is a brief summary of the referenced standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. This specification covers grades of hot-formed welded and seamless high-strength low-alloy square, rectangular, round, or special shape structural tubing for welded, riveted, or bolted construction of bridges and buildings and for general structural purposes.
