Cryogenic Metal Treatment / Hardening Equipment

CES designs, engineers, builds, installs and services Batch and Continuous Cryogenic Equipment for the Metal Treatment Industry. Through sub-zero quenching as an additional stage in the heat treatment process, it is possible to reduce internal stress and increase the wear resistance of ferrous steels. On top of that the cryogenic hardening optimizes the dimensional stability of tool's steel by transformating the retained austenite to martensite and simultaneously releases and evenly distributes small carbide particles throughout the material.

CES builds cryogenic hardening and tempering chambers in different sizes and models as well as Continuous Cryogenic Equipment. The working temperature range of our chambers lies between -185C [-300F] and +600C [+1120F] with a very tight temperature uniformity. A wide range of system management and temperature control units are available, from conventional to PLC based controls.
