Abstract
Cast iron containing magnesium, in amounts such as to produce spheroidal graphite in the iron as cast if the iron is gray or to cause carbides to break down to spheroidal graphite on subsequent heat treatment if the iron is white, is produced by first making an iron containing more magnesium than is required by introducing the magnesium to molten iron in a closed vessel and mixing the product with an iron to which no magnesium has been added. The magnesium rich iron may be produced by the process claimed in Specification 743,456.
