SM520 steel plate is a Japanese standard welded structural steel plate, and its yield value will decrease as the thickness of the material increases. SM means the Japanese standard, and 520 is the tensile strength of the steel plate. The implementation standard is JISG31013, SM520/SM570.
The heat treatment process of SM520/SM570 steel plate is generally hot rolling or normalizing heat treatment process. The shape, size, weight and allowable error of SM520/SM570 steel plate materials shall comply with JISG3192, JISG3193 and JISG3194 standards. If there is no special technical requirement, the material thickness of SM520/SM570 steel plate is generally in accordance with the allowable error of group A in JISG3193 standard.
SM520B/SM520C steel plate has good comprehensive mechanical properties, good low temperature performance, good plasticity and weldability. SM520B/SM520C steel plate is used for medium and low pressure vessels, oil tanks, vehicles, cranes, mining machinery, power stations, bridges and other structures bearing dynamic loads, Mechanical parts, building structures, general metal structural parts. SM520B/SM520C steel plate is used in hot rolling or normalizing state, and can be used in various structures in cold regions above -40.
