20# steel plate is a high-quality low-carbon carbon steel plate, cold extruded, carburized and hardened steel. P355GH steel application, 20# steel has low strength, good toughness, plasticity and weldability. The tensile strength is 253-500MPa, and the elongation is ≥24%. 20# steel performance is basically similar to 15# steel, but the strength is slightly higher. The cold-drawing or normalizing state of the cutting process is better than the annealing state. 20# steel is used to manufacture various mechanical parts with high toughness under hot rolling or normalizing state, which require high toughness.Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team. It is a professional p355gh steel application production team combining theory and practice. With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of p355gh steel application leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the p355gh steel application steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.Modern steel-making steel purification facilities and advanced quality control methods have been perfected. Rolling steel can be produced according to controlled rolling and controlled cooling, normalizing, and quenching and tempering processes to produce σs 390-685Mpa series products. p355gh steel application, Low alloy high strength structural steel plate has stable quality, good wear resistance and low temperature toughness. It can be widely used in the manufacture of mining machinery, engineering machinery, high-rise buildings and heavy vehicles.As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality p355gh steel application products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
