Generally, the production process of A588 grade B heavy plate seamless steel tube can be divided into cold rolling and hot rolling. The production process of cold-rolled seamless steel tube is generally more complicated than that of hot rolling. The tube blank must be first rolled by three rolls, and then be subject to sizing test and cutting after extrusion. Then enter the annealing process. In appearance, the cold-rolled seamless steel tube is shorter than the hot-rolled seamless steel tube, and the wall thickness of the cold-rolled seamless steel tube is generally smaller than that of the hot-rolled seamless steel tube, but the surface looks brighter than the thick wall seamless steel tube, the surface is not too rough, and the diameter is not too much burr.
The main advantage of 20CrMo alloy steel plate is reflected in its various physical and chemical properties. For 20CrMo alloy plate, the main component is alloy, and the physical and chemical properties of alloy A588 grade B heavy plate are generally, a single metal is better, and its performance is stronger. The main features of 20CrMo alloy steel plate are high precision, rigidity, high temperature and high pressure resistance, not easy to corrode and other characteristics.
