The atmosphere is a limiting factor in the heat treatment process. This is because a chemical reaction can occur between the hot surface of the material and oxygen and other components, as well as the inclusion of gas molecules. The use of inert gas does not eliminate potential problems. Only vacuum conditions allow precise processing without the risk of a reaction between the material and its environment. We offer vacuum installations for heat treatment processes such as annealing, hardening, brazing, sintering and vacuum carburising.
