Vacuum heat treatment technology is also a treatment process, but it is compared with the TD process there are differences, of course, also has its own set of distinct advantages, including a good effect of oxidation; and a reduction of the role of rust, saving roughing process workpiece. As a result, not only can save material consumption, but also reduce costs.

Vacuum heat treatment with a vacuum degassing, degreasing effect but there is no risk of hydrogen embrittlement, to prevent the surface of the workpiece material refractory metal embrittlement, effective measures to improve the purity of the material and the surface properties. Mainly because of having a vacuum heat treatment quenching deformation characteristics, can reduce the stress of conventional quenching distortion correction exists, reducing the possibility of breakage of the workpiece during use, extending its life.
In addition, it has good stability and repeatability, once the process is determined, as long as the input process procedures, heat treatment operations will run automatically. Avoid quality fluctuation amount slightly conventional heat treatment process instability, is a real safe, pollution-free, energy-saving ideal technique.
