The Specification of Casting Steel Ball
Low Chrome Casting Steel Ball
Chrome Concentration is 1-3%, hardness ≥ HRC 45, impact value ≥1J/CM^2, this steel ball is called low chrome grinding balls, which is made by smelting in intermediate frequency electric furnace, metal mould or sand casting process. It applies to metallurgic mines and slag industries where no high grinding accuracy or wearability is required.
