After comprehensive and professional training such as customer service, the customer service team has more strict discipline in the management of customer service team to ensure that customer service personnel respond to customers with a professional attitude. A process supervision system has been set up to let each customer supervise the process of the system with usThe pre cooling direct quenching and low temperature tempering of wear-resistant composite plate can reduce the quenching deformation of the workpiece, and the residual austenite content in the carburized layer can also be slightly reduced. The surface hardness of the hardfacing wear-resistant composite plate, DH32 hull structure steel is slightly increased, but the austenite grain does not change. It is widely used in various tools of fine grain steel manufacturing.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℃. DH32 hull structure steel, 20CrMo steel pipe is generally used in quenching and tempering state.Company management philosophy: integrity-based, service-oriented, excellence, affinity symbiosis. Based on quality, continuously create maximum value for customers. Always have a grateful heart, thank the society, thank family and friends for their support and help to the development of the company, thank customers for their trust, thank colleagues for their cooperation, and thank competitors for their supervision.
