Vacuum Passthrough Hardening Tempering Furnaces
After vacuum quenching and tempering (vacuum aging), it is mainly used for tool steel, die steel, high speed steel, high strength steel, titanium and other materials. The purpose of vacuum tempering is to keep the advantages of material vacuum quenching (products are not oxidized, decarburized, non carbon, bright surface, non corrosive pollution, etc.).
