Investigations on the effect of cryogenic treatment on the behaviour of En 19 steel

Abstract

It has been observed quite a long time that the wear and corrosion are the most common problems in the mineral processing equipments The screening equipment automotive shafts crankshafts connecting rods axle gears are typically made of En19 steel The reasons for the frequent failure of these components are due to impact wear and fatigue Frequent replacement of these components increases the equipment downtime and maintenance cost thereby reducing the process efficiency Cryogenic treatment of steels plays an important role in developing the tribological properties of steels One of the most common claims in cryogenic treatment is an increase in wear resistance of steels Supplementing cryogenic treatment to conventional heat treatment process will aid the manufacturers to attain better wear resistance of steel components Cryogenic treatment helps to transform the retained austenite to martensite along with the carbide precipitations Hence an effort has been made to investigate the influence of cryogenic treatment on En 19 steel
