Cryogenic treatment uses liquid nitrogen (-196℃)as refrigerant as well as specific timing to relieve residual stresses when processing metals, to create very fine eta carbides, increase fatigue life and abrasion resistance, and convert retained austenite to martensite. the benefit of this process are increased part life, less wear and improved performance of the metal parts, such as cutters,gears, brakes,etc. Except of that, cryogenic treatment can also used in the field of mechanical engineering, medical research,plant preservation, aerospace and laboratory,etc.
