Since cast iron is a compound material of steel and graphite, its mechanical properties change according to the amount, form and distribution of the graphite. In this paper, the effects of graphite on the mechanical properties were kept constant. That is, the eutectic graphitization ability (EGA) in gray cast iron was limited to approximately 50%, and in the case of spheroidal graphite cast iron, the nodularity was maintained above 80%.  This paper presents a method of determining the mechanical properties from the hardness. First, the relationship between hardness and tensile strength was established and then the relationship between tensile strength and various mechanical properties was determined. From the data thus obtained it was possible to determine the various mechanical properties only from the hardness.
