Further transformation to improve the performance of metal materials. After the cryogenic treatment of metal, the wear resistance, toughness and dimensional stability of metal workpieces can be significantly improved, and the service life of the workpiece is doubled. metal Cryogenic treatment equipment: Improve the hardness and strength of the workpiece Guarantee the dimensional accuracy of the workpiece Improve the wear resistance of the workpiece Improve the impact toughness of the workpiece Improve internal stress distribution and increase fatigue strength Improve workpiece corrosion resistance

The so-called cryogenic treatment is to use liquid nitrogen (-196 C) as a cooling medium to continue the cooling process of the quenched metal material to a temperature far below room temperature, which promotes the acquisition of residual austenite after conventional heat treatment. Further transformation to improve the performance of metal materials. After the cryogenic treatment of metal, the wear resistance, toughness and dimensional stability of metal workpieces can be significantly improved, and the service life of the workpiece is doubled. Measuring Cryogenic Treatment--Technical Application Cryogenic processing equipment is a new technology that places the workpiece to be processed in a specific and controlled low-temperature environment, changes the microstructure of the material, and improves or improves the performance of the material. The temperature of cryogenic treatment is generally -100 C ~ -196 C. Due to the change of the microstructure of the treated material in a low temperature environment, the macroscopic performance is the surface hardness, impact toughness, wear resistance, dimensional stability, Improvements and improvements in strength, residual stress, etc. At present, our research on cryogenically treated materials involves: High-speed steel W9, W6, mold steel 3Cr13, carburized steel 20CrMnTi, high-chromium cast iron, high vanadium cast iron to improve the wear resistance of the workpiece and extend the service life; hard alloys such as aluminum alloys 2A11 and 2A12 to improve the dimensional stability of materials; Low temperature impact toughness of 42CrMo, 35CrMo.
