Low chromium alloy wear resistant steel ball

Detail
Detail

The surface hardness of low chromium cast steel ball produced by Jinan Houde wear resistant material Co., Ltd. is more than 45hrc. It has no deformation, no out of roundness, good toughness, less breakage and uniform hardness gradient distribution. The recovery rate of concentrate is high, the working efficiency of mill is improved, and the service time of mill liner is effectively extended. It is widely used in mineral processing, cement, building materials, chemical industry, ceramics and other industries.
