SM570 steel is a low-carbon high-strength structural steel that can be processed with good cold forming properties. SM570 HSLA steel plate is usually provided in normal rolling or controlled rolling delivery state. SM570 steel is a hot rolled steel used for welded structures, and SM570 steel is a material grade and name defined in the JIS G3106 standard. JIS G3106 is a Japanese material standard for welded structural steel plates, sheets and strips of hot-rolled steel used in building structures and engineering structures.
HSLA steels are classified as a separate steel category, which is similar to as-rolled mild-carbon steel with enhanced mechanical properties obtained by the addition of small amounts of alloys and, perhaps, special processing techniques such as controlled rolling and accelerated cooling methods.
Applications of SM570 HSLA steels include oil and gas pipelines, heavy-duty highway and off-road vehicles, construction and farm machinery, industrial equipment, storage tanks, mine and railroad cars, barges and dredges, snowmobiles, lawn mowers, and passenger car components. Bridges, offshore structures, power transmission towers, light poles, and building beams and panels are additional uses of these steels.
