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 A588 grade A HSLA steel plate 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 A588 grade A HSLA steel plate leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.
20Mn2 steel is used to manufacture carburized parts with low requirements on the surface and core, and with a cross-sectional diameter of less than 50mm, such as carburized pinions, small shafts, and low-demand pistons instead of 20Cr steel in the manufacture of automobiles, tractors and machine tools Pins, cross pin heads, diesel engine sleeves, valve jacks, gearbox levers, steel sleeves, etc. In addition, this kind of steel can also be used to make riveting weldments, screws, nuts, etc. under hot rolling and normalizing conditions.
A588 grade A HSLA steel plate, 20CrMo alloy steel plate has high hardenability, no temper brittleness, good weldability, little tendency of cold cracking, good machinability and cold strain plasticity. 20CrMo alloy steel plate is generally used in the state of quenching and tempering or carburizing and quenching. 20CrMo alloy steel plate is used to manufacture high-pressure pipes, fasteners and carburized parts, such as gears and shafts, working in non corrosive medium and medium containing mixture of nitrogen and hydrogen under 250 ℃.
Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while A588 grade A HSLA steel plate steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of A588 grade A HSLA steel plate steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.
