Deep Cryogenic Treatment

Deep Cryogenic Treatment is a material science and involves the process of reducing the temperature of components over an extended period of time to extreme cold levels. Liquid Nitrogen is a common fuel for the process being relatively inexpensive and making up more than 70% of our atmosphere thus having a reduced effect on the environment.

As the LN2 (Liquid Nitrogen) boils off from liquid to gas at around -195 degrees celsius, the components in its proximity are also cooled. The process is controlled by microprocessors in order that thermal shock is not generated at the same time resulting in damage to components.

As the material cools its molecular structure is drawn together through contraction and stress and dislocation brought about by production methods is removed or reduced. Other effects are the production of martensite, named after the German metallurgist Adolf Martens (1850-1914)in Carbon Steels, and the precipitation of Eta type Carbides.

The process has a wide range of applications from industrial tooling to improvement of musical signal transmission.It has been found and proved that cryogenic treatment improves wear resistance of many alloy steels to a great extent
