Crafted with exacting standards, the sprocket body for the carrier is made from high-quality materials such as 40Mn2, 40MnB, and 50Mn, chosen to meet the diverse needs of various operational environments. The wheel body undergoes a detailed sequence of forging and normalization, complemented by a cutting-edge spray heating and quenching process. This ensures the tread surface achieves a hardness range of HRC52 to HRC62, with a hardened depth of 7-10mm and a minimum hardness of HRC45.
