Abstract

PURPOSE: To obtain vermicular graphite cast iron contg. partially hypereutectoid spheroidal graphite with extended lower limit of the vermiculating element content by adding a restricted amount of Si, Ca, an alkaline earth metal except Ca and a rare earth metal.
CONSTITUTION: This vermicular graphite cast iron contg. partially hypereutectoid spheroidal graphite consists of 2.0W4.0% C, 0.5W4.0% Si, 0.001W0.03% Ca, 0.05W1.0% one or more among Al, Sb, As, Bi, Pb, Se, Te, Sn and Ti, ≤0.03% S, ≤0.008% O, <0.03% alkaline earth metal except Ca, ≤0.17% of ≥1 kind of rare earth metal and the balance essentially Fe. By this composition the lower limit of the vermiculating element content is extended, so case iron having the desired structure composed of partial spheroidal graphite and vermicular graphite can be cast well using molten metal obtd. by melting pig iron, scrap iron, etc. as starting material.
