Abstract: 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:Group 1: 2.5 to 4.0% carbon; 0.3 to 0.8% silicon; 0.3 to 0.8% manganese; 0.75 to 2.0% nickel; 0 to 0.75% chromium.Group 2: 3.0 to 4.5% carbon; 0.3 to 0.8% silicon; 0.3 to 1.0% manganese; 0 to 0.8% molybdenum; and 0.3 to 1.0% copper.Group 3: 3.0 to 4.5% carbon; 0.3 to 0.8% silicon; 0.3 to 1.0% manganese; and 0.3 to 0.

Abstract: 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.

Abstract: A low alloy white cast iron has been developed for wear resistance applications. The alloy consists essentially of about 2 to 4% carbon, 0.3 to 1.5% silicon, 0.5 to 1.5% manganese, 0.5 to 1.5% copper and 0.25 to 1% molybdenum, the remainder being substantially iron except for incidental impurities commonly found in cast iron. The preferred alloy composition is 2.5 to 3% carbon, 0.6 to 0.9% silicon, about 1% manganese, about 1% copper and about 0.5% molybdenum, the rest being substantially iron. The process for manufacturing the above wear resistant alloy consists in melting an alloy having the composition mentioned above, casting such alloy into moulds to produce a desired product such as grinding balls or slugs, shaking the product out of the moulds at a temperature of 750.degree. C. or higher, preferably about 900.degree. C. and cooling the product at a rate of 2.degree. to 15.degree. C./sec., preferably 5.degree. to 10.degree. C./sec.
