Wear resistant white, martensitic cast iron (Ni-Hardcast iron) containing nickeland chromium as the main alloying elements. The incorportaed iron carbides and special carbides in particular reduce masive abrasive wear due to minerals.

Possible applications of the materials include grinding tools, crushing, mixing and conveyor systems as well as pump construction.
