S.g iron rolls are available in a wide range of hardness & composition for a variety of application. These rolls are essentially an indefinite chill type material, but with the graphite in nodularform instead offlake and having alloyed with higher % of nickel & molybdenum along with carbon. The matrix structure varies from ferrito-pearlitic, pearlitic to bainitic & martensitic together with different carbide contents and graphite in the form of spheroidsnodules. Some critical grades are heat treated for higher strength.
