The material of the carrier roller is 40Mn2, 40MnB, 50Mn, etc. according to the working conditions. After precision forging and normalizing, the wheel body is heated and spray quenched as a whole. The surface hardness of the tread reaches HCR52-62, and the hardening depth reaches more than 7-10mm (HRC45), ensuring longer impact resistance on the outside and inside of the wheel body.
