Cast Steel Ball:

Multi-Alloy Cast Steel Ball

Multi-Alloy Cast Steel Ball, widely used in powder preparation and  superfinishing for  the devices of cement, building materials, metallurgy, thermal power plant, ceramics, refractories and the other industries. The products have excellent surface finish,high load carrying capacity, high intensity, high hardness, high wear ability, high temperature resistance, impact resistance, low damage percentage and so many other features. They can help corporations to promote production, reduce production cost, reduce labor intensity of the workers.

All products can be designed according to customers requirements.
