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 A283 Gr D ms steel sheet 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 A283 Gr D ms steel sheet leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.
10CrMo9-10 steel plate is a kind of European standard pressure vessel steel plate, which is heat-resistant and high-pressure resistant boiler steel plate, belonging to alloy pressure vessel steel plate; 10CrMo9-10 steel plate is mainly used for power station boiler drum and steam boiler equipment. The A283 Gr D ms steel sheet delivery state of 10CrMo9-10 steel plate is usually normalizing + tempering.
The advantages of A283 Gr D ms steel sheet, seamless steel pipe are high pressure resistance, good toughness, long pipe section and few joints. It is widely used and the rolling technology of domestic steel mills is also very mature. Compared with round steel, the weight of seamless steel pipe is lighter under the same strength. Seamless steel pipe manufacturing ring parts, can improve the utilization of materials, simplify the manufacturing process, save materials and processing time. Compared with the welded pipe, there is no weld on the outer surface of seamless steel pipe, and it has good compression resistance.
There is an inherent difference between the cold forming properties of low-alloy high-strength steel and carbon structural steel. First of all, a certain amount of permanent deformation of low-alloy high-strength steel requires greater force than A283 Gr D ms steel sheet, carbon structural steel of the same size. Second, when low-alloy high-strength steel is formed, a slightly larger allowable amount for springback should be given. According to experience, unless the low-alloy high-strength steel is processed to control the shape of inclusions, it is necessary to use a larger bending radius than carbon structural steel during cold forming.
The chemical composition of Q345D seamless steel pipe is as follows: C ≤ 0.18, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.030, S≤ 0.025, Nb ≤ 0.07, V ≤ 0.15, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.50, Cu ≤ 0.30, N ≤ 0.012, Mo ≤ 0.10, Al ≥ 0.015. A283 Gr D ms steel sheet, Q345D seamless steel pipe has good comprehensive mechanical properties, low temperature impact toughness, corrosion resistance, cold stamping, machinability and weldability. Q345D seamless steel pipe is widely used in welding structures, such as bridges, vehicles, ships, pipelines, boilers, large vessels, etc..
The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
