Experimental Investigation on the Effect of Deep Cryogenic Treatment on 100Cr6 Bearing Steel

Abstract

R Sri Siva, M Shunmuga Priyan

Cryogenic treatment is the process of cooling a material to extremely low temperatures to generate enhanced mechanical and physical properties. The present investigation examines the effect of deep cryogenic treatment on the enhancement of mechanical properties, such as wear resistance, corrosion resistance, tensile strength and impact strength of the plunger material 100Cr6 bearing steel. The improvement in the wear resistance, corrosion resistance, tensile strength and impact strength of the deep cryogenically treated samples over the conventionally heat-treated ones, is 50%, 26%, 13% and 27% respectively. This study suggests that the formation of very small carbides dispersed in the tempered martensite structure, can be the main reason for the enhancement of certain mechanical properties, along with the retained austenite transformations.
