ZY-019 Mold Steel Cryogenic Treatment

Cryogenic treatment of mold steel is a new technology that places the processed workpiece in a specific and controllable low-temperature environment, causing changes in the microstructure of the material and improving its 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.

Cryogenic treatment parameters for mold steel:

1. The model, effective size, capacity, and load-bearing capacity are shown in the table above

2. Temperature range: -190 ℃ to+200 ℃

3. Heating and cooling speed: 1 ℃/min to 10 ℃/min

4. Door opening method: negotiable

5. Temperature uniformity: ± 2 ℃

6. Temperature control accuracy: ± 1 ℃

7. Outer surface temperature of the box: ≤ room temperature ± 5 ℃
