Generally, the production process of EN steel grade S235J2 plates 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.

A good EN steel grade S235J2 plates, automobile steel plate material must have a certain elastic performance, otherwise it will affect the overall comfort performance and aesthetics of the car, especially in the process of driving on some uneven roads. The good quality automobile steel plate can play a certain role in shock absorption, make the driver driving more comfortable. Especially for some drivers with long running length, it can reduce driving fatigue. The high-strength automobile steel plate is stronger in material, and it is more solid and firm when used in the overall frame and other parts of automobile manufacturing, which also improves the quality of the entire automobile.

Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched EN steel grade S235J2 plates increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of EN steel grade S235J2 plates during tempering, while tempering determines the performance and life of the workpiece.

The chemical composition of 20CrMo steel pipe is 0.17-0.24, Si: 0.17-0.37, Mn: 0.40-0.70, Cr: 0.80-1.10, Mo: 0.15-0.25. Mechanical properties of 20CrMo steel pipe: tensile strength 410 Mpa; yield strength: 265mpa; elongation after fracture: 24; reduction of area: 60; impact absorption energy: 110J. 20CrMo steel pipe belongs to alloy structure steel pipe, which has high thermal strength, good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance at 500-520℃. EN steel grade S235J2 plates, 20CrMo steel pipe is generally used in quenching and tempering state.
