| Abstract: | A new crusher hammer was made. The composition was optimized by alloying and then it experienced heat treatment technology. The results were as follows, this low carbon and medium alloy steel has good properties. The hardness of the steel is HRC >51, impact toughness is ak>141 J / cm2. After heat treatment the microstructure composed of the mixture of tempered martensite, a small amount of residual austenite and carbide dispersion. Compared with the crusher hammer produced by high manganese steel, the properties were greatly improved. |
