Grinding Steel Balls chrome grinding balls grinding media
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.
Manganese steel grinding ball I
Manganese steel grinding ball I is popular in Korea, Japan and North Korea, impact value is more than 12J/CM^2, manganese content is about 0.6-1.0%. This is the cheapest one in the manganese grinding balls. The performance as follow:
| Chemical Composition | C(%) | Si(%) | Mn(%) | Cr(%) | Cu(%) | Mo(%) | P(%) | S(%) |
