Heat treatment process is a resultant process to improve the mechanical and metallurgical properties of the material. Deep cryogenic treatment is not an alternative process to the heat treatment process it is a complimentary process to the heat treatment and it affects the entire cross section of the material. Deep cryogenic treatment is a heat treatment process where the material is subjected to comparatively extreme low temperature condition in order to enhance the mechanical and metallurgical behaviors of the material. Low alloyed case hardening steels used for manufacturing of parts which required to withstand high operating condition such as axle drives, gears & shafts. In this proposed work 20MnCr5 steel has been subjected to Deep Cryogenic Treatment at different soaking temperature and period. A comparative characterization study has to be conducted, before and after the cryogenic treatment, to investigate the behavior of materials.

Keywords : Deep Cryogenic Treatment, Soaking Period, Soaking Temperature.
