High manganese steel hammers are particularly suitable for crushing conditions that are subject to strong impacts due to their excellent work hardening properties. This type of hammer performs particularly well in the following crushers: First, large hammer crushers that process high-hardness materials (such as granite and basalt). When the rotor linear speed exceeds 50m/s, the hardness of the high manganese steel hammer can be increased from HB200 to HB500 or more after the working surface is impacted, forming a self-reinforced wear-resistant layer. Secondly, single-stage hammer crushers for mining use. When crushing materials with a compressive strength of more than 200MPa, the toughness of high manganese steel can effectively prevent the hammer from breaking. High manganese steel hammers are also suitable for impact crushers when crushing construction waste containing more iron impurities, because they can withstand the accidental impact of metal foreign bodies. However, it should be noted that when crushing materials with strong abrasiveness but insufficient impact force (such as quartz sand), high manganese steel cannot be fully hardened and wears faster. In terms of economy, although the initial cost of high manganese steel hammers is low, its cost-effectiveness is significant under applicable working conditions, and it is particularly suitable for crushing production lines with large output and severe impact. During regular inspections, if the working surface of the hammer head is found to have uneven hardening marks, it proves that the material selection is appropriate.
