Product Description Good quality high chromium cast iron grinding media steel ball low chrome alloyed casting grinding balls for silver mineProduct DescriptionForged Rolling Steel Ball DescriptionHeating the customed steel until the temperature reaches 1100C( +-50C) in the way of hot rolling and forging,the rollig forging machinery will put pressure on the metal blank and producing a grinding ball with certain mechanical property, shape and size . This is our processing methods of the grinding balls.We can produce three types of wear-resistant steel balls: forged steel balls, cast steel balls,and hot-rolled steel balls.Grinding Steel Ball FeaturesRongsheng is able to manufacture accurate-size, high-roundness,high-hard rolling balls. They have great wear resistance, difficult deformation and less broken, uniform hardness distribution, high impact toughness( over 12j/cm2).Product ApplicationGrinding Steel Ball ApplicationsGrinding steel ball Mainly suitable for industries such as mining, steel, chemical industry, cement plants, power plants, ball coal machine, semi-automatic ball mills, and ball mills,etc.Product ParametersDiameter Tolerance and RoundnessNominal diameter30405060708090Tolerance(mm)±2+3,-2Roundness (%)≤2≤3Nominal diameter100110120125150Tolerance(mm)+4,-3+5,-4Roundness (%)≤4≤5Chemical CompositionBrandC(%)Si(%)Mn(%)Cr(%)Cu(%)Mo(%)P(%)S(%)Ni(%)45#0.42-0.500.17-0.370.5-0.800-0.250-0.250-0.300-0.0350-0.0350-0.3040Mn0.37-0.440.17-0.370.7-1.00-0.250-0.250-0.300-0.0350-0.0350-0.3050Mn0.48-0.560.17-0.370.60-1.00-0.250-0.250-0.300-0.0350-0.0350-0.3060Mn0.57-0.650.17-0.370.70-1.00-0.250-0.250-0.300-0.0350-0.0350-0.3065Mn0.62-0.700.17-0.370.90-1.00-0.250-0.250-0.300-0.0350-0.0350-0.3070Mn0.67-0.750.17-0.370.90-1.200-0.250-0.250-0.300-0.0350-0.0350-0.3040Cr0.37-0.450.17-0.370.50-0.80.80-1.10-0.250-0.300-0.0350-0.0350-0.3042CrMo0.38-0.450.17-0.370.50-0.800.90-1.20-0.030.15-0.250-0.0350-0.0350-0.3070Cr20.65-0.750.20-0.300.75-0.900.55-0.700-0.250-0.300-0.0300-0.0300-0.3040Mn20.37-0.440.17-0.371.4-1.80-0.250-0.250-0.300-0.0350-0.300-0.3070Mn20.65-0.750.20-0.451.4-1.80-0.250-0.250-0.300-0.0350-0.0300-0.30B-10.52-0.650.17-0.370.60-1.20-0.250-0.250-0.300-0.0350-0.0350-0.30B-20.70-0.800.17-0.370.70-0.800.50-0.600-0.250-0.300-0.0350-0.0350-0.30B-30.58-0.661.2-1.60.65-0.800.70-0.900-0.250-0.300-0.0350-0.0350-0.30B-40.60-0.651.6-1.70.7-0.80.7-0.80-0.250-0.300-0.0350-0.0350-0.30B-60.75-0.850.2-0.400.9-1.00.85-0.950-0.250.06-0.130-0.03502-0.0350.06-0.13B-6A0.82-0.950.20-0.400.92-1.020.80-0.950-0.250.06-0.100-0.0350-0.0350.06-0.10B-70.35-0.400.17-0.370.7-0.80.9-1.00-0.250-0.300-0.0350-0.0350-0.30BU0.95-1.050.17-0.370.9-1.100.40-0.600-0.150-0.050-0.0350-0.0350-0.30Gr150.95-1.050.15-0.350.20-0.401.30-1.650-0.250-0.100-0.0270-0.0200-0.10Technical SpecificationBrandBreakage rateHardness(HRC)Impact value(J/cm2)Drop timesMicro structure45#<1%≥45≥12≥8000M+C40Mn<1%≥50≥12≥10000M+C50Mn<1%≥55≥12≥10000M+C60Mn<1%≥55≥12≥12000M+C65Mn<1%≥58≥12≥12000M+C70Mn<1%≥60≥12≥12000M+C40Cr<1%≥55≥12≥12000M+C42CrMo<1%≥55≥12≥12000M+C70Cr2<1%≥58≥12≥12000M+C40Mn2<1%≥55≥12≥12000M+C70Mn2<1%≥58≥12≥12000M+CB-1<1%≥55≥12≥12000M+CB-2<1%≥58≥12≥15000M+CB-3<1%≥60≥12≥15000M+CB-4<1%≥60≥12≥15000M+CB-6<1%≥60≥12≥15000M+CB-6A<1%≥60≥12≥15000M+CB-7<1%≥60≥12≥15000M+CBU<1%≥60≥12≥15000M+CGr15<1%≥60≥12≥15000M+CPackaging & Shipping1.Professional export transport packaging2.
