The mechanical properties of SG cast iron can be improved by changing the process parameters like melting of base
iron scrap, nodulisation treatment, percentages of Nodulariser, magnesium treatment, inoculation process, type of inoculant.
percentages of inoculant as well as pouring practices etc. The quality of casting checked with tensile strength, hardness test,
wear test & microstructure analysis. Also, in micro structure of SG iron extra amount of hard carbide generates. Due to this
hard carbide structure, there are some of mechanical properties affects like reduction in ductility and machinability. The main
aim behind this paper is to present literature review on effects of various process parameters on mechanical properties and
microstructural properties of spheroidal graphite cast irons
