Roll property
During nodular cast iron add much more Ni, Mo alloy, can get excellent pearlite, bainite or martensite matrix organization, however graphite morphology is globular, conductive performance is good, tensile strength is higher. Through change organization for pearlite, martensite and acicular nodular iron chemical composition and heat treatment process, improve the abrasion resistance.
