With our special heat treatment, the grinding rod has low wear rate, high hardness (about 45-55 hrc) and good toughness.
After removing the internal stress by quenching and tempering, our grinding rod will not break, bent or thin for two sides. The good resistance will help customers decrease the total costs. With the powerful technological strength, we are capable to meet customers’ requirements for any specification, which increases flexibility largely and reduces unnecessary waste.
