High strength quenched and tempered structural steel. It has high strength and toughness, high hardenability, medium cold deformation plasticity, and good machinability. There is a tendency of temper brittleness, and the transverse impact toughness is poor. The welding performance is good, but when the thickness is greater than 3mm, it should be preheated to 150 ℃ first, and heat treatment is required after welding. Use after general tempering
