A process for producing a low alloy white cast iron is disclosed. The process comprises the steps of selecting one of a group of four alloying elements for a nickel, molybdenum/copper or modified low alloy iron; the four alloying groups consisting essentially, by weight percent of about:

Low white cast iron grinding slug

Process for producing a low alloy white cast iron

A low alloy white cast iron is disclosed. The alloy consists essentially, in weight percent, of about 2.5 to 4% carbon, 0.3 to 0.8% silicon, 0.3 to 1.0% manganese, and 1.7 to 3.5% nickel, the rest being iron except for incidental impurities commonly found in cast iron. The alloy has a microstructure consisting essentially of martensite and carbide and a minimum hardness of 600 B.H.N.
