研制了一种新型复合锤头磨损部分用铸态高铬锰耐磨铸铁,锤柄用普通低碳钢。这种高铬锰铸铁是用锰取代高铬钼铸铁中的钼,生产成本低,高铬锰铸铁耐磨性比高锰钢提高2倍,与高铬钼耐磨性相当,该材料具有广泛的应用前景和推广价值。
Developed a new type of composite hammer wear part of the cast high chromium manganese wear-resistant cast iron, hammer handle with ordinary mild steel. This high chromium cast iron replaces molybdenum in high chromium molybdenum cast iron with manganese and has a low production cost. The high chromium cast manganese cast iron has a higher wear resistance than high manganese steel by a factor of 2 and a wear resistance comparable to that of high chromium molybdenum. The application prospect and promotion value.
