Vacuum Tempering

ECM vacuum tempering furnaces are used for high-speed and alloy steels to produce a scale-free finish. Tempering is almost always required after hardening to reduce the hardness (and brittleness) of the treated material to a desirable level - both in an atmosphere and vacuum furnace. Generally, it is not necessary to use vacuum tempering after vacuum hardening (i.e. conventional tempering is most often used). Vacuum tempering may be used on high value products, when a completely clean surface appearance is required.

ECM USA also supplies regular tempers as part of our fully integrated and automated packages for heat treatment facilities.
