Product Details

Introduction of the product

With its chromium content, the 1-32% Cr Casting Grinding Ball delivers exceptional durability and wear resistance. The higher chromium balls exhibit excellent hardness and corrosion resistance, significantly reducing the wear rate during grinding operations. Even in harsh conditions, these grinding balls maintain their shape and integrity for longer periods, contributing to reduced replacement costs and improved productivity. Lower chromium balls provide cost-effective solutions without sacrificing the necessary performance for less abrasive grinding tasks.
