The role of cryogenic processing of die material
The continuation of cryogenic treatment after quenching workpiece cooling process, the application in the mold industry mainly embodied in the cold work die steel and high speed steel, bearing steel, cold work mould and mould parts have cryogenic technology application case.
Deep cold will change some mechanical properties, and the main effect will be as follows: Enhance the hardness and strength of the workpiece Ensure the precision of the workpiece Improve the wear resistance of the workpiece Improve the impact toughness of the workpiece Improve the internal stress distribution of the workpiece and increase the fatigue strength Improve the corrosion resistance of the workpiece.
Cryogenic processing can improve the performance of various materials. In the mould materials, it is mainly possible to improve the wearability, the prolonged impact fatigue strength, the ductility of the material and the internal deformation.
