国内抗磨抗冲击零件大多采用高锰钢,目前,高铬白口铸铁取代了一部分抗磨高锰钢件。利用双金属铸造工艺生产的复合材料,将拓宽高铬铸铁的应用领域,取代高锰钢零件,还可以节约钢材50％以上。1988年,江西省科委要求省机械科学研究所与浒坑钨矿合作,开展“双金属复合铸造工艺” Domestic anti-wear parts are mostly anti-impact high-manganese steel, at present, high-chromium white cast iron to replace some of the high manganese steel parts. The use of bimetal castings produced composite materials, will broaden the application of high-chromium cast iron, instead of high-manganese steel parts, but also can save more than 50% of steel. In 1988, Jiangxi Provincial Science and Technology Commission requested the Institute of Machinery Science and Hu Hang mine tungsten cooperation, to carry out the “bimetal composite casting process”
