<p>PROBLEM TO BE SOLVED: To provide a casting suitable for a wear resistant material such as agricultural machines, e.g. the edges of a subsoiler, a rotary, a plough, or the like, and a sprocket, a pump case for raw sewage, a livestock excreta pump, scattering machine parts, a transporting pipe for sludge, a chip crusher and a caterpillar, further reduced in cost and capable of recycling as the material in which the welding of a wear resistant hard member is needless, further, the inside is excellent in strength and toughness-ductility, and the surface is excellent in wear resistance. SOLUTION: This wear resistant material composed of austempered spheroidal graphite cast iron has a humid wear face.</p> |
