Low alloy high strength SM520B steel plate

SM520B is a Japanese standard low-alloy high-strength steel plate, and the executive standard is JIS G3101 rolled steels for general structures, such as buildings, bridges, ships, rail vehicles and other structures.

Heat treatment of SM520B steel plate: hot rolled steel plate/normalized steel plate.
Performance characteristics of SM520B steel plate: its yield value will decrease with the increase of material thickness.

For the detection of SM520B/SM520C steel, on the one hand, whether the element content of the steel meets the requirements of the Japanese standard, and on the other hand, whether the mechanical properties (yield strength, tensile test) of the steel meet the standards through professional institutions are the most important. The application of SM520B/SM520C steel includes carburized or cyanide parts with low core strength requirements, pull rods, connecting rods, hooks, couplers, bolts and nuts, sleeves, shafts and weldments, etc.

The SM520B/SM520C steel has good comprehensive mechanical properties, low temperature properties, good plasticity and weldability. It can be used as structures, mechanical parts, building structures, and general metal structures bearing dynamic loads, such as medium and low pressure vessels, oil tanks, vehicles, cranes, mining machinery, power plants, bridges. It can be used in hot rolling or normalizing conditions, and can be used for various structures in cold regions above - 40℃.
