The cold cutting properties of steel bonded tungsten carbide are far less than that of molten steel. Because of the high hardness, high strength, high wear resistance, large deformation resistance and large cutting resistance, the tungsten carbide billet must be spheroidizing and annealed before cutting. There are about 0.5 ~1.0 mm hard shells on the surface of the sintered alloy billets. Although the machinability is still poor after annealing treatment, the hard shell of this layer is removed before cold cutting, and then machined according to the normal procedure.
