The oldest high-alloy white irons produced commercially were the high-chromium (28% Cr) white irons. The high-chromium white irons have excellent abrasion resistance and are used effectively in slurry pumps, brick molds, coal-grinding mills, rolling mill rolls, shot blasting equipment, and components for quarrying, hard-rock mining and milling.

Article shared by: . These cast irons have high abrasion-resistance, and can be readily cast in shapes required in machinery used for crushing and grinding, etc. Abrasion-resistance increases with the increase of hardness due to the increase of the volume of the eutectic carbides (alloy eutectic carbides are much harder than iron carbide).

Cast iron's properties are changed by adding various alloying elements, or alloyants.Next to carbon, silicon is the most important alloyant because it forces carbon out of solution. A low percentage of silicon allows carbon to remain in solution forming iron carbide and the production of white cast iron.

Sep 29, 2000 · In this study, the abrasive wear performance of different heat-treated boron alloyed high chromium cast iron ore grinding balls was examined. Laboratory tests were carried out using pin-on-disc and rubber wheel abrasive testers. Three different loads (32.3, 53.7 and 83.7 N) were applied for two-body high stress abrasion tests (on pin-on-disc).
