The main applications of vacuum heat treatment

Release time：2023-06-08

After vacuum heat treatment, the parts have small distortion, high quality, and the process itself is flexible and pollution-free. Therefore, vacuum heat treatment is not only a means of heat treatment for certain special alloys, but also has been applied in the heat treatment of general engineering steel, especially tools, molds, and precision couplings. After vacuum heat treatment, the service life is greatly improved compared to general heat treatment. For example, some molds after vacuum heat treatment have a lifespan that is 40-400% higher than the original salt bath treatment, while many tools can have a lifespan that can be increased by about 3-4 times. In addition, the vacuum heating furnace can operate at higher temperatures and the workpiece can maintain a clean surface, thus accelerating the adsorption and reaction processes of chemical heat treatment. Therefore, certain chemical heat treatments, such as carburizing, nitriding, chromizing, boronizing, and multicomponent co infiltration, can achieve faster and better results.
