bp370 steel heat treatment main useage

BP370 steel heat treatment,20# steel plate is a high-quality low-carbon carbon steel plate, cold extruded, carburized and hardened steel. , 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,BP370 steel heat treatment.BP370 steel heat treatment,We will return our customers with zealous service attitude, high quality products and favorable price. We have been accumulating, perfecting, developing and expanding constantly. We have huge steel products stock. We have won the trust and support of our customers with high-quality service and excellent product quality. The company adheres to the development concept of honesty and win-win cooperation. We are willing to form an alliance with like-minded partners to work together for development and common progress.BP370 steel heat treatmentTempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.BP370 steel heat treatment,The microstructure of the quenched and tempered alloy steel after conventional heat treatment is tempered sorbite. For parts with wear-resistant surface (such as gears and spindles), induction heating surface quenching and low-temperature tempering are carried out, and the surface structure is tempered martensite. The surface hardness can reach 55HRC-58HRC. After quenching and tempering, the yield strength of quenched and tempered alloy steel is about 800MPa, the impact toughness is 800kJ / m2, and the core hardness is 22HRC - 25HRC. If the cross-section size is large but not quenched, the properties will be significantly reduced.The company specializes in heavy plate cutting, carbon steel pplate processing, carbon plate welding processing and sales of wide and thick steel plates. It has high-quality CNC steel plate cutting and processing equipment, a professional technical personnel team, and supporting logistics distribution and after-sales service system. BBN company provides customers with solutions at low prices, high quality, and fast response service.
