The development of vacuum quenching technology for 40cr precision tubes mainly lies in the development of gas cooled quenching furnaces with excellent performance and a single workstation. The aforementioned dual chamber furnace can also be used for gas quenching, but the dual station operation makes it difficult to produce large quantities of furnaces and can easily cause workpiece deformation or change workpiece orientation during high-temperature movement to increase quenching deformation.

You can judge from the material of the 40cr precision tube. Generally, alloy steel is used to make 40cr precision tubes. You can effectively judge from several aspects such as weight, color, and glossiness. You can also directly check the corresponding product composition on the product packaging to see if the 40cr precision tube material has reliable performance and materials.

The 40cr precision tube has the advantages of withstanding high pressure without leakage, high precision, high smoothness, no deformation during cold bending, no expansion, and no cracks during flattening.

Before passivation and acid washing treatment, the surface of the 40cr precision tube must be subjected to degreasing and degreasing processes, and further components must be welded before degreasing treatment to avoid carbon buildup in the pickup at high temperatures.

The 40cr precision tube has superior performance compared to ordinary seamless tubes, with dense metal ratio, flexible adjustment of oil pressure in the common rail chamber based on the requirements of engine load, economy, and emissions, especially optimizing the low-speed performance of the engine.

40cr precision tubes are mainly used for mechanical structures and hydraulic equipment. Using 40cr precision tubes to manufacture mechanical structures or hydraulic equipment can greatly save machining hours, improve material utilization, and also contribute to improving product quality.
