Cryogenic Treatment - An Overview

Cryogenic treatment is the process of subjecting materials to cryogenic (very low) temperatures up to -190 degrees C.

Cryogenic treatment is used to relieve residual stresses and to increase wear resistance.  The component to be treated is immersed in a bath of liquid nitrogen or any other refrigerant and slowly cooled till the target temperature.  It is then gradually brought back to room temperature. 

Corrosion resistance is also improved as a result of cryogenic treatment.  Electrical and mechanical properties are also improved.
