Abstract

Hardening is one of the heat treatment process, which is done for improving some desirable mechanical properties of carbon steel. Medium carbon steel is used as various structural parts in industries. Among those, chain conveyor pin, etc are required hardening to increase the surface hardness and to resist wear. But due to hardening some other mechanical properties are being changed. In this present experimental work, changes of mechanical properties like UTS, impact strength, and fatigue strength of medium carbon steel due to hardening have been studied. Hardness of specimen has been changed by water quenching and oil quenching. Subsequently micro structural study under SEM has been carried out for fatigue failed surface. Significant changes have been observed in both mechanical strength level and micro structural level.

Keywords
