ICDP rolls for bar mill

Properties
             The shell has a remarkable mechanical performance. With virtually no fall off in hardness due to the quantity of graphite remains
   basically unchanged throughout the working layer. The hardness of roll depends mainly on the type of matrix, namely sorbite or  marte
   nsite.
