The request for developing more sophisticated properties of Spheroidal Graphite Cast Iron resistant to high temperature are growing storonger year by year. There has however been no dramatic change in measures for decades under which cast iron with a high Si contents would be used as the material resistant to oxidation at high temperatures. For years Mo has thus played a major role as an additive for the purpose of improving strength at high temperatures. In previous work, oxidation resistant properties at high temperature were studied by using the high Si contents (4.0%) S. G. cast iron specimens (test pieces) with co-composition of 0.6%Ni, 0.2%Cr, and 0.5%Cu. 0.2%Cr of molten iron of added solely showed the best improvement in all the data investigated throughout our fundamental experiments. The effects of Si, Cr and RE were studied as additives for improving resistant properties against high temperature in this work, while co-composition was also studied to meet demands for the development of high quality S. G. Cast Iron.
