Low Chrome Cast Grinding Iron Ball
Low chrome Cast Grinding Ball are very affordable, but which still have well wear resistance and won`t break, mostly used to cement plants and coal mining. Low chrome cast iron ball chemical is C:2.2-3.4, Si:≤1.2, Mn:0.5-1.5, P:≤0.06, S:≤0.06, Cr:1.0-1.5, while the hardness of the low chromium ball is up to 45–52 HRC, with 20 mm as the minimum and 140 mm as the maximum diameter. Breakage is lower than 1%, and impact is ≥2Ak.J/cm2. Drop test is higher than 8000 times in the 6.5m high platform.
