碳含量对低铬抗磨铸钢硬度和韧性的影响

The Effect of Carbon Content ob the Hardness and Toughness of Low-Chromium Wear-resistant Cast Steel

低格抗磨锈钢具有较好的综合力学性能．本文研究了这种好钢的硬度和韧性防碳含量的变化规律．可根据抗磨件的工况条件和性能要求来选择不同的碳含量，对生产现场具有指导性的意义．

Low-chromium Wear－ resistant cast steel has higher synthetical mechanicalpropemes．The influence of different carbon content on both the hardness and toughness of thiscast steel has been studied ．The results show that proper carbon content can be chosed under thedifferent condition and properteies of the wear－ resistant parts .The conclusion is usehl for the working sites．
