ABSTRACT:
A ferrosilicon inoculant for gray cast iron containing between 0.1 to 10% strontium, less than 0.35% calcium and either 0.1 to 15% zirconium, 0.1 to 20% titanium or a mixture of both zirconium and titanium with the strontium. The inoculant, method for producing the inoculant, method for inoculating the melt and a gray cast iron inoculated with the inoculant are covered.
