CCS Approval Certificated Q420B grade steel

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 Q420B grade steel 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 Q420B grade steel leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.

The company has an entrepreneurial team composed of highly educated and high-quality talents, whose leaders graduated from famous universities. As the first group of teams engaged in e-commerce industry in China, it witnessed the rapid development of e-commerce, accumulated rich steel professional knowledge and formed a scientific management system.

Both 14Cr1MoR pressure vessel steel and 15CrMoR pressure vessel steel belong to Cr-Mo hydrogen resistant steel, and they are special steel in strict sense. Q420B grade steel, Cr-Mo hydrogen resistant steel is suitable for petrochemical, nuclear power, steam turbine cylinder block, thermal power and other large-scale equipment with high temperature and high pressure and connected with hydrogen or hydrogen mixed medium. Moreover, 15CrMoR pressure vessel steel has high endurance strength below 550 °C.

Weathering steel generally adopts the process route of fine material into the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and cooling. The scrap steel is added into the furnace together with the charge, and smelted according to the conventional process. After the Q420B grade steel steel is tapped, deoxidizers and alloys are added. After the molten steel is treated with argon blowing, the molten steel is cast. By adding rare earth elements to the steel, the Q420B grade steel weathering steel is purified and the content of inclusions is greatly reduced.

In January 2019, one of our Vietnam customer purchased 395.62 tons Q345B steel plate Q420B grade steel for their construction project, we prepared all the goods ready within 5 days, and supplied the goods with painting sand blasting to SA2.5 Q420B grade steel and priming gray oxide primer, and arrange shipment in time. Meet the customer urgent delivery request.
