"Cryogenic treatment, which is sometimes called cryogenic processing, utilizes ultra-cold temperatures to modify the micro-structure of metals and other materials. Cryogenic treatment has been widely adopted as a cost reduction and performance enhancing technology. Cryo treatment is also used as an enabling technology, when its stress relieving benefits are utilized to permit the fabrication (or machining) of critical tolerance parts.

The Cryo treatment process uses sub-zero temperatures down to –300ВєF to modify the micro-structure of the material. Cryogenic treatment promotes additional transformations in metals. It ultimately improves the performance of the metal.

Cryo treatment is an extension of the heat-treating process that further enhances metals in the following ways:

Relieves residual stresses
Promotes a more uniform micro-structure
Precipitates eta-carbides in steels for increased resistance to wear
Cryo treated metals enjoy the following benefits:

Longer life due to reduced wear
Less failures due to cracking that result from the propagation of stress lines
Improved thermal properties
Better electrical properties with reduced electrical resistance
Reduced coefficient of friction on polished metals
Less creep & walk, and improved flatness for critical tolerance parts
Easier machining, polishing and grinding for better edges and finishes"
