Vacuum Heat Treatment

vacuum heat treatment


Our vacuum heat treatment services are one of the best processes available. Vacuum heat treating is when metal parts are exposed to temperatures of heat in order to change their properties.  A hard or partial pressure vacuum austenitizes steel parts. This protects the surface of the parts during this operation. These processes allow for shorter carburizing cycles, a reduction in overall processing time and smaller gas consumption.

There are numerous treatments involving our vacuum processes that we use. These treatments achieve higher strength, better wear resistance and improve the corrosion behavior of the subjected material. At SST, our treatments offer the best protection against oxidation while remaining extremely cost-efficient. Learn more about our vacuum heat treatment services.

Vacuum Carburize

A gas carburizing process in which steel is austenitized in a vacuum, carburized in a partial pressure of hydrocarbon gas, diffused in vacuum, then quenched in gas or oil

Vacuum Harden-Nitrogen Quench

Vacuum hardening utilizes a heating operation in the absence of oxygen which prevents oxidation and decarburization.  With the use of gas quenching, distortion is reduced when compared to oil.

Vacuum Anneal

Vacuum annealing (also known as bright anneal) is used to reduce internal stress and improve workability.  It can also be applied to finished parts without effecting the parts appearance.

Vacuum Braze

A metal joining process in which two base metals are joined together by heating to a suitable temperature and using a filler metal. This takes place in a vacuum furnace that uses low atmospheric pressures instead of a protective gas atmosphere.
