... Abstract Malleable iron is a cast ferrous metal that is initially produced as white cast iron and is then heat treated to convert the carbon-containing phase from iron carbide to a nodular form of graphite called temper carbon. This article provides a discussion on the melting practices, heat...

... this manner. Cast irons contain much more carbon than steels, so the implications of decarburization are somewhat different, even if the physical chemistry is much the same. Decarburization sometimes is used to advantage in processing cast iron. White-coring malleable cast iron (“white heart”) is...
