Aim of this research paper is to investigate the effect of heat treatment on mechanical propertiesof Mild Steel (ASTM A36). Heat treatment was carried out in a furnace at a temperature of 800oC, after heating at such temperature quenching was carried out using brine solution. It was observed that on heating the mild steel resembles the properties of cast iron along with increase in boiling temperature.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 mild steel. To investigate the microstructure of the heat treated surface, grinding with the help of rough 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 Mild steel.
