摘要
研制的中铬抗磨铸钢的硬度HRC≥60、冲击韧性a_k≥20J/cm^2.用作锤头其使用寿命是高锰钢的2.4倍,而成本仅比高锰钢提高25%.
The hardness of HRC60 or more and impact toughness of 20 J/cm2 or more were achieved with medium-chromium wear-resistant cast steel, the service life of which used for hammers is 2.4 times as long as that of high-manganese steel,but the production cost is increased only 25%.
