Ni-Hard is a white cast iron, alloyed with nickel and chromium suitable for low impact, sliding abrasion for both wet and dry applications. Ni-Hard is an extremely wear resistant material, cast in forms and shapes which are ideal for use in abrasive and wear environments and applications. Read More > White Cast Iron
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.

high alloy white irons contain chromium to prevent the formation of graphite on solidification, stabilize the carbide and to form chromium carbides which are harder than iron ones. Most of them also contain nickel, molybdenum, copper or combinations of these alloying elements in order to prevent
May 14, 2014· The structure of white cast iron consists of pearlite and ledeburite, a eutectic mixture of pearlite (converted from austenite) and cementite. Cementite is hard and brittle and dominates the microstructure of white cast iron. Thus, white cast iron is hard and brittle and has a white crystalline fracture because it is essentially free of graphite.
