近十几年来,高铬白口铸铁已得到人们的普遍重视与广泛应用。已经证明,在高应力和低应力磨料磨损方面,高铬白口铸铁的耐磨性比高锰钢要高。高铬白口铸铁已被公认为是第三代抗磨材料,常用的高铬白口铸铁含铬量为14～20%;含碳量为2.4～3.6%,其它成分有钼、镍、硅、锰和铜等如表1所示。此材料具有以下优点:①高铬铸铁易形
In recent ten years, high-chrome white cast iron has been widely valued and widely used by people. It has been demonstrated that high chromium white cast iron has higher wear resistance than high manganese steel in terms of high stress and low stress abrasive wear. High chromium white cast iron has been recognized as the third generation of anti-wear materials, commonly used high-chromium white cast iron chromium content of 14 to 20%; carbon content of 2.4 to 3.6%, the other components of molybdenum, nickel, silicon , Manganese and copper as shown in Table 1. This material has the following advantages: ① high-chromium cast iron easy to shape
