30CrMnSi high strength quenched and tempered steel plate has high strength and toughness, high hardenability, moderate cold deformation and good cutting performance. 30CrMnSi steel material has temper brittleness and transverse impact toughness. The welding performance of 30CrMnSi steel is good. But when the thickness is greater than 3mm, the 30CrMnSi high strength quenched and tempered steel plate should be preheated to 150 degrees, and heat treatment is needed after welding.
