Heat treatment of metal under vacuum results in a metal with desired properties. In the heat treatment chamber, elements that are naturally found in air are completely removed. A vacuum heat treatment process provides several benefits, from high thermal efficiency to improved properties of material, such as toughness, plasticity, etc. The workpieces treated using a vacuum heat treatment equipment will not have any carbon, and oxidation. Metal-forming and processing companies can buy from us vacuum tempering furnace, vacuum gas quenching furnace, vacuum annealing furnace and more, depending upon the treatment process.
