ABSTRACT
This paper presents the results of an experimental investigation of the mechanical properties of spheroidal graphite (SG) iron where varying percentage of magnesium using as an inoculants. Total four test samples were carried out. The specimens were subjected to tensile strength, yield strength, percentage of elongation, hardness and percentage of modularity. The results indicate that the prediction percentages of Mg are not accurate. By help of formula, prepared four samples of different percentage of Mg (0.025%, 0.030%, 0.035%, and 0.040). Based on the experimental results this paper evaluate that S.G iron having the Mg about 0.035% in its final composition will give good mechanical properties as well as the desirable microstructure having the higher number of nodules.
