Ultra deep cold treatment box YDDS-49

The ultra deep cold treatment box YDSL-49 places the processed workpiece in a specific and controllable low-temperature environment, causing changes in the microstructure of the material and achieving a new technology to improve or enhance material properties. The temperature for cryogenic treatment is generally between -100 ℃ and -196 ℃. The microstructure of the treated material changes at low temperatures, resulting in macroscopic improvements in surface hardness, impact toughness, wear resistance, dimensional stability, strength, residual stress, and other aspects of the material.

At present, our research on cryogenic treatment materials involves:
High speed steels W9 and W6, mold steel 3Cr13, carburizing steel 20CrMnTi, high chromium cast iron, and high vanadium cast iron are used to improve the wear resistance of workpieces and extend their service life; Hard alloy, etc
Aluminum alloys 2A11 and 2A12 that improve material dimensional stability;
42CrMo and 35CrMo are used to improve the low-temperature impact toughness of materials.
