Vacuum hardening process is a type of heat treatment used especially for hardening tool or high speed steels. The difference from the treatment process is heating and cooling environments. Heating is carried out in a vacuum-free oxygen-free environment, so that no scale or carburization or decarburization occurs on the surface of the part. The design of the vacuum heat treatment furnaces is suitable for increasing the high temperatures required by the tool steels heat treatment.
