Vacuum heat treatment products

Vacuum heat treatment technology has a series of advantages, such as no oxidation, no decarburization, degassing, degreasing, good surface quality, small deformation, excellent comprehensive mechanical properties of heat treatment parts, long service life, energy saving, etc. Recently, it has made rapid development in China. At present, it has been used in aerospace industry, tooling, precision parts, oil pump nozzles and other mechanical parts with high quality requirements Widely used.

Heat treatment is not only a necessary means of heat treatment for some special alloys, but also has been widely used in the heat treatment of general engineering steel, especially for tools, moulds and precision joints. As we all know, the parts after vacuum heat treatment have small deformation, good quality, flexible technology and no pollution.

The service life of vacuum heat treatment is longer than that of general heat treatment. For example, the life of some dies after vacuum heat treatment is 40-400% longer than that of the original salt bath treatment, and the life of many tools can be increased by 3-4 times. In addition, the vacuum furnace can work at a higher temperature and keep the surface of the workpiece clean, thus speeding up the adsorption and reaction process of chemical heat treatment. Therefore, some chemical heat treatment, such as carburizing, nitriding, chromizing, boronizing, multi-element co infiltration, can get faster and better results.
