Abstract: A method for casting wear resistant parts which is capable of forming a hardened portion at a desired position with ease, whereby a wear resistant part can be obtained which has both wear resistance and toughness. To this end, the method includes the steps of filling the cacity of a holding member (16), which can be melted into molten steel, with a hardened portion forming material (19) comprising superhard particles (17), placing the holding member (16) which has been so filled with the hardened portion forming material (19) in a casting mold (10), pouring molten steel into the casting mold (10), thereby causing not only the holding member (16) to be melted into molten steel but also the superhard particles (17) to be dispersed, and solidifying the molten steel. In addition, the hardened portion forming material (19) can be constituted by superhard particles (17) and graphite powder (18) and/or metallic powder.
