The investigation, pressed steel can scraps (P-SCS) and shredded steel can scraps (S-SCS) were melted for casting spheroidal graphite cast iron with a high frequency induction furnace, was conducted to grasp chemical composition and mechanical properties. The Al mixed from the P-SCS increased up to 4.25% at 80% of the compounding rate. Moreover, Al mixed from the S-SCS increased up to 1.72% at 80% of the compounding rate. In addition, it approved that P-SCS addition makes Cr, Sn, and Ti increase into a molten cast iron. When it increased S-SCS addition, however, Ti brought about the result that Ti did not increase. The tensile strength and brinell hardness showed the inclination to go up in connection with the increase in P-SCS and S-SCS addition. The elongation showed the inclination that decreases in connection with the increase in P-SCS and S-SCS addition. Blending more than 20% of P-SCS, and 60% of S-SCS compounding rate generated the quasi-flaky graphite. By these results, it is considered that P-SCS of less than 10% compounding rate and S-SCS of less than 40% compounding rate are utilized as a raw material for a spheroidal graphite cast iron.
