Introduction
Casting steel ball diameter from 20-150mm with high hardness, low wear,
Low broken rate, strong heat resistant and corrosion resistance, chromium content
From 1%-28%, hrc45-63, .Detailed specifications can be customized according
To customer demand. It is particularly used in cement industry working in the grinder with high temperature, high crushing and strong abrasion .

The grinding ball with chromium content 1% - 3% and hardness hrc =45 called
Low chromium alloy cast ball. Low chromium ball is produced by the intermediate frequency electric furnace smelting, metal mold or sand casting .

Features
Good toughness, low abrasion rate, low broken rate , low chromium ball hardness can reach 45-55hrc
