Products introduction

Forged steel ball is divided into carbon grinding steel ball, manganese grinding steel ball and special grinding steel ball. Forged steel ball is one of our advantage products. Diameter 20-70mm and 80-150mm steel ball are produced respectively by advanced automatic hot rolling and hot forging steel ball production line. Huafu grinding balls with uniform hardness in a high efficiency due to its advanced quenching technology. In advanced, these grinding balls feature high accurate dimensions, rounded geometry shape, high hardness and good mechanical properties, wear - resistance, no deformation, no breakage.
