Abstract

Cryogenic treatment is process done after conventional heat treatment process in material processing technology.It is a permanent treatment done only once which affects the whole section of the component. It is not acoatings of superior materials over other metal surfaces that only affects the surface of components. Cryogenic treatments are proved to be a good way to decrease the retained austenite content and improve the performance of materials by improving its martensite structure. Objectives of cryogenic treatments are to increase material’s strength, hardness, wear resistance, ductility, & toughness, to obtain fine grain size, to remove internal stresses, to improve machinability, cutting propertiesof tools, to improve surface properties, electrical properties & magnetic properties.
