Listing ID #930659

Get access to the best quality S G Iron Rolls from us. The Pearlitic spheroidal graphite rolls have a thick layer of cast iron with nodular graphite. The name of such roll is based on the fact that the material consists of nodular graphite and carbides in a pearlitic matrix. The softest grades have a pearlitic matrix containing ferrite around the graphite nodules, while the higher hardness grades have a complete pearlitic matrix. The carbide content increases proportionately with the hardness.
