Name Designation Chemical composition(%) C Si Mn Cr Mo Cu Ni P S low Chrome Cast Gringing Balls ZQCr2 2.5-3.2 0.5-1.3 0.5-1.5 0.8-3.0 0-0.3 0-0.3 ≤0.3 ≤0.1 ≤0.1 Our factory production's ball mill steel ball may widely apply in profession and so on cement building materials, metal mine, coal tar thermal power, chemical engineering, ceramics powder body preparations and the superfine intensive processing. Product degree of hardness is high, wears and tears lowly, toughness is good, stave few, the spheroid skin hardness will enhance further in the use process, the resistance to wear strengthens, simultaneously may sharpen the grinding machine productivity, enhances the cement to compare the surface area and the ore concentrate returns-ratio.
