    Abstract: A method and cast wear resistant component made of an alloy that includes carbon, tungsten, chromium, and cobalt with the balance essentially iron and other alloying components made using waste, surplus or worn-out cemented carbide product, such as cemented carbide cutting tool inserts. In one method, the alloy further includes silicon, manganese, nickel, titanium, and molybdenum. In practicing the method, pieces of waste, surplus or worn-out cemented carbide product having tungsten carbide (WC) are added to a cast iron alloy melt. The melt includes enough chromium to control solubility of the WC. In one method, precipitated carbide structure having chromium and carbon is produced with tungsten in the melt being substitutionally dissolved. In one implementation, tungsten is substitutionally dissolved in a lattice of the precipitated carbide structure. Carbide can be added to the melt via super inoculation. The cast wear resistant component can be a cutting tool.
