ABSTRACT: 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.
