Steel tracks are generally made of high manganese steel.
This is because high manganese steel has a prominent feature, that is, it undergoes impact hardening under the action of impact load, making it form a surface layer that is both hard and wear-resistant, while still maintaining the toughness and plasticity of its inner layer.
Manufacturing includes the following steps: round bar blanking, heating, precision forging, overall quenching, tempering, machining of shaft holes, sleeve holes, bolt holes, magnetic particle inspection and assembly.
