Abstract : 16MnCr5 is a low alloy steel which is widely used in manufacturing industrial and automobile components such as gears, shafts, crankshafts, etc. which are subjected to high wear. This, in turn, will lead to deviation from ideal working condition and hence will lead to reliability issues. In this work, an experimental investigation on the effect of cryogenic treatment on the mechanical properties of 16MnCr5 will be studied. In cryogenic treatment, materials are taken to sub-zero temperatures and kept therein for predetermined time periods. Based on the temperature up to which the material is taken to, cryogenic treatment is divided into two types: Shallow and Deep. Two different treatment paths were chosen for the study: Carburizing followed by cryogenic treatment and cryogenic treatment alone. The results revealed that carburized and then cryogenically treated 16MnCr5 samples showed an improvement in hardness and wear resistance whereas the toughness showed a gradual decrease with increase in soaking time. Cryogenic treatment as such did not bring any significant improvement in mechanical properties
