Abstract

A method of producing iron castings with undercooled graphite consists in the addition to the molten metal, before pouring, of not more than 1 per cent zirconium, or not more than 0.5 per cent bismuth, sufficient manganese being included in the molten metal, when sulphur is present, to balance the said sulphur. The addition of zirconium or bismuth may be followed by bubbling carbon dioxide through the molten metal. The zirconium may be added as pure zirconium metal or known zirconium alloy. Specification 425,227 is referred to.
