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
The industry is widely used in aerospace, cables,brake rotors, metals, steel parts, rollers, bearings,hardware, tools, molds, friction coupling parts, precision and so on.
