Product Description
Spheroidal graphite cast iron roll
Properties
Thanks to its higher content of Ni and Mo alloys, pearlite, basinite and martensite matrixes with excellent performance are produced. The
graphite si spherical form, demonstraing good heat transfer property and high tensile strength. Through changing the struture into basinite
of marensite matrix, chemical compostion of needly-like spherical iron of heat treatment, a dense reticular primary cementite with high wear-
resistance is produced.
