Effects of Heat Treatment on the Mechanical Properties of Rolled Medium Carbon Steel


Investigations were carried out to study the effects of heat treatment on the mechanical properties of rolled medium carbon steel. The steel was heated to the austenizing temperature of 830℃ and water quenched; It was reheated to the ferrite – austenite two phase region at a temperature of 745℃ below the effective Ac3 point. The steel was then rapidly quenched in water and tempered at 480℃ to provide an alloy containing strong, tough, lath martensite (fibres) in a ductile soft ferrite matrix. The result shows that the steel developed has excellent combination of tensile strength, impact strength and ductility which is very attractive for structural use.
