HSLA High-strength low-alloy steels are used for their higher strength and atmospheric corrosion resistance. Tensile test and bend test shall be performed for the material to conform to the requirements specified.
This abstract is a brief summary of the referenced standard. Ashm the results of the mechanical tests representing any heat do not conform to a requirement, retests shall be made. The tubing shall be made by the seamless, furnace-buttwelded continuous-weldedor hot-stretch-reduced electric-resistance-welded process. ASTM A is used in welded, bolted, or riveted structures, especially bridges and buildings in which its strength and durability is required. If the results of the mechanical tests representing any heat do not conform to a requirement, retests shall be made.
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.

Combining values from the two systems may result in asgm with the standard. When the steel is used in welded construction, the welding procedure shall be suitable for the steel and the intended service.
ASTM A HSLA Steel Grade III, Thickness 19 to 38 mm (3/4 to in.)
Data sheets for overmetals, plastics, ceramics, and composites. We advise that you only use the original value or one of its raw conversions in your calculations to minimize rounding error.
When properly exposed to the atmosphere, Grades Ia and Ib can be used bare unpainted for many applications. Combining values from the two systems astn result in non-conformance with the standard. The values stated in zstm system may not be exact equivalents; therefore, each system shall be used independently of the other.
They can be considered to be microalloyed steel and are designed for mechanical rather than compositional specs. 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.
The tubing shall be made by the seamless, furnace-buttwelded continuous-weldedor hot-stretch-reduced electric-resistance-welded process. Grade II has atmospheric corrosion resistance equivalent to that of carbon steel with copper 0. 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.
