This hard outside and tough inside characteristic makes it both wear-resistant and impact-resistant. Although high manganese steel has gradually been replaced by other materials in some applications, it still has irreplaceable advantages under strong impact loads. In addition, steel that has been quenched and ground also has high wear resistance.
