Resistance to corrosion was reduced bJabrading the rust, and increasing frequency of abrasion increased the corrosion rate, except for gray cast iron. Resistance to abrasion alone was found to be related to a defined equivalent carbon content of the steels tested rather than to their hardness. Three white cast irons showed exceptional resistance to
