Abstract

This invention relates to cast iron and more particularly to the improvement in the toughness and abrasive resistance of white cast iron along with a significant increase in tensile strength. More specifically, the present invention relates to a new white cast iron composition and a process for producing such cast iron having improved toughness, ductility and tensile strength while retaining desirable abrasive resistance through modification of the carbide morphology.
