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 sa573 gr.70 mild steel hot rolled heavy 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 sa573 gr.70 mild steel hot rolled heavy plate leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.
Shipbuilding steel plates are used to manufacture marine and inland watercraft hulls, requiring high strength, plasticity, toughness, cold bending performance, welding performance, and corrosion resistance. The company provides common shipboard grades such as Grade A, Grade B, Grade D, Grade E, Grade AH32, AH36, AH40, DH32, DH36, DH40, EH32, EH36, EH40, FH32, sa573 gr.70 mild steel hot rolled heavy plate FH36, FH40.
The yield strength of Q690D steel plate is 690 Mpa and the impact temperature is - 20℃. sa573 gr.70 mild steel hot rolled heavy plate, Q690D steel plate has high strength, good plasticity and toughness, good weldability and good cold and hot performance. Q690D steel plate is mainly used to manufacture various large engineering structural components and construction machinery. Because of its high strength and good toughness, Q690D steel plate can reduce the self weight of components and meet the requirements of large-scale and lightweight engineering components and equipment under the condition of ensuring strength, stiffness and reliability.
Heat treatment process: heat treatment refers to a kind of process operation in which the metal or alloy can change the internal structure through certain heating, heat preservation and cooling methods in the solid range to obtain the required performance. sa573 gr.70 mild steel hot rolled heavy plate Heat treatment process refers to the ability to change the microstructure and properties of sa573 gr.70 mild steel hot rolled heavy plate after heat treatment, including hardenability, hardenability, temper brittleness, etc.
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℃. sa573 gr.70 mild steel hot rolled heavy plate, 20CrMo steel pipe is generally used in quenching and tempering state.
Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.
