【Abstract】 The properties of steels for toothed cutters used for coal mining machines at home and abroad are measured and analysed. The microstructure, hardness, impact toughness, abrasive wear resistance etc. are investigated preliminarily. The relationship among wear resistance with microstructure, hardness, impact toughness of the steels are discussed.更多还原
