Aim of this research paper is to investigate the effect of heat treatment on microstructural behavior of Cast Iron (ASTM A48). For investigating the effect heat treatment was carried out in stages. In first stage material is heated in a furnace at a temperature of 850°C, followed by quenching inside the furnace. Further in second stage material was heated at a temperature of 900°C, followed by quenching with the help of cooled still air. It was observed that on heating, cast iron resembles the properties of mild steel along with increase in melting temperature. It reduces the cost to be bear for making mild steel.Various mechanical properties such as. Tensile strength, yield strength, modulus of elasticity, bulk modulus, shear modulus, Poisson’s ratio, elongation percentage & hardness are analyzed to investigate the effect of heat treatment on the cast iron. To analyze the microstructure of the heat-treated surface, grinding with the help of rough emery paper & fine emery paper and by using alumina paste on double disk polishing machine was carried out. It was revealed that heat treatment produces significant effect on properties of cast iron.
