Effect of Tempering Behavior on Heat Treated Medium Carbon (C 35 Mn 75) Steel

Abstract

Investigations were carried out to study the effects of heat treatment on the mechanical properties of medium carbon steel. Samples of medium carbon steel were examined after heating at 9000C and soaked for 60 minutes in a muffle furnace and quenched in oil. The mechanical behavior of the samples was investigated using universal tensile testing machine for tensile test and Rockwell hardness method for hardness testing. The hardness values and tensile strength of the quenched samples were relatively higher than those of the as-received samples, suggesting improved mechanical properties. The mechanical properties such as ductility, toughness, strength, hardness and tensile strength can easily be modified by heat treating the medium carbon steel to suit a particular design purpose. Tensile test specimens were produced from medium carbon steel and were subjected to various forms of heat treatment processes like annealing, normalizing, hardening and tempering. Results showed that the mechanical properties of medium carbon steel can be changed and improved by various heat treatments for a particular application
