SM570 steel plate belongs to low-alloy high-strength steel plate. Low-alloy high-strength steel is a kind of engineering structure developed by adding a small amount of Mn, Si and trace amounts of Nb, V, Ti, Al and other alloying elements on the basis of carbon structural steel Use steel. The so-called low alloy means that the total amount of alloy elements in the steel does not exceed 3%. High strength is relative to carbon engineering structural steel.
SM570 steel plate has high strength and good fatigue resistance; SM570 steel plate has high toughness and low brittle transition temperature; SM570 steel plate has good cold forming performance and welding performance; SM570 steel plate has good corrosion resistance and certain wear resistance.
Therefore, SM570 steel plate is suitable for all kinds of lifting cranes, pump trucks, heavy vehicles, high-temperature fans, coal mine hydraulic supports, steel structures, etc. SM570 steel plates are widely used in construction machinery, bridges, containers, vehicles, electrical equipment and other structural parts.
