Sub-Zero Treatment equipment for Steel Alloys  high quality blades and knives

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.

the working temperature: room temp.~-196℃

 or Working temperature― +300℃～-196℃

The insulation layer――the thermal-protective coating is an ultra-low temperature thermal insulation materials Made in Germany BSF with Multilayer composite structure with extremely low heat transfer coefficient, which can effectively block the exchange of heat and cold inside and outside the box.

Temperature control system ――German ultra-low temperature control technology, leading low-temperature processing technology and control system

 liquid nitrogen solenoid valve――JAKSA (imported from the Germany) ultra low solenoid valve can ensure open normally at -196℃
