Pearlitic Nodular Cast Iron Roll (SGP roll)
Grade properties: Adding more Ni and Mo alloys to ductile iron can obtain excellent pearlite, bainite, and martensite matrix structures, while graphite is spherical in shape, has good thermal conductivity, and has high tensile strength. By changing the structure to Bainite The chemical composition and heat treatment process of solid, martensite and acicular ductile iron can obtain very dense network of primary cementite to improve wear resistance.
