High Chromium Cast Steel Rolls The hardness of High Chromium Cast Steel Rolls rolls is as high as 65-80 HSC.Its matrix gives itself excellent wear resistance and good fire-crack resistance. HiCrS rolls have a low carbon content range of about 10%. An important characteristic of HCrS is that the mill is not required to adjust special water cooling conditions. And in the rolling process these rolls can form oxide film to improve surface quality of rolled products.These rolls are suitable for both 2-Hi roughing and early stand of 4-Hi finishing for hot strip mills.Chemical Composition %SymbolCSiMnCrNiMoHCrS1.00-1.800.40-1.000.50-1.008.00-15.000.50-1.501.50-4.50Prosperities&ApplicationSymbolHardnessHSTensile StrengthMPaApplicationHCrS70-85≥450(core)Roughing work rolls for hot strip mills,Website:http://www.kdroll.com, vertical rolls; universal section mills
