The grinding ball with 7% - 10%, usually HRC ≥46 called medium
chromium alloy ball,hardness can reach 47-55HRC.
It is widely used in mining, cement and building materials, thermal
power, metallurgy and chemical industry and area, big, small,
mainly used in various specifications of dry wet mill, to crush the
role, is an ideal wear-resistant materials.
Good toughness, low abrasion, low broken rate of chromium in chromium alloy casting;
