First of all, SM400B low alloy steel plate has high strength and excellent plasticity. The yield strength of the steel is 245MPa, the tensile strength is 400-510MPa, and the yield ratio is also very high. At the same time, its plasticity is also very good, cold bending performance is good, can continue to carry out deep processing, such as cold forming, cutting, bending and so on. Second, the SM400B performs reliably at low temperatures. This steel can still maintain enough toughness and robustness at a low temperature environment of -20°C, without problems such as fracture or deformation.
In addition, SM400B low alloy steel plate also has good corrosion resistance and wear resistance. Its REDOX reaction is relatively inert, not easy to be oxidized, so it has good corrosion resistance in atmospheric environment and water environment. At the same time, the surface hardness of the steel is high, has a certain wear resistance, and can resist wear and abrasion to a certain extent.
Finally, the SM400B low alloy steel plate is welding performance is also excellent. It can adapt to different welding processes, including manual arc welding, submerged arc welding, argon arc welding, etc., welding joint strength is high, not easy to crack.
