Abstract

PURPOSE: To produce the ferrite-type spheroidal graphite cast iron having excellent ductility and toughness in the state as cast, by inoculating 30% of the necessary quantity of Si directly before casting after the spheroidizing treatment of graphite of the cast iron has been carried out.
