Cryogenic equipment It is a new technology to place the processed workpiece in a specific and controllable low temperature environment, so as to change the microstructure of the material and improve the performance of the material. The temperature of cryogenic treatment is generally -At 100 ℃~- 196 ℃, the microstructure of the treated material has changed under the low temperature environment, which is shown in the improvement of the surface hardness, impact toughness, wear resistance, dimensional stability, strength, residual stress, etc. At present, our research on cryogenic treatment materials involves:
High speed steel for improving wear resistance of workpiece and prolonging service life W9、W6， Die steel 3Cr13, carburized steel 20CrMnTi, high chromium cast iron, high vanadium cast iron; Hard alloy and other aluminum alloys 2A11 and 2A12 that improve the dimensional stability of materials; 42CrMo, 35CrMo to improve the low-temperature impact toughness of materials.
