Balls are hardened by microalloying steel and heat treatment. The technology for producing iron balls is more complicated (centrifugal casting); they are used primarily for grinding cement and non-ferrous metal ores. The wear resistance of such products is increased by alloying cast iron with chromium, vanadium, molybdenum and nickel.
