Graphitic Cast Steel Roll

It is a kind of quality between conventional cast iron and cast steel, its carbon content is usually between 1.2 ~ 2.3%. It is of high strength and toughness of cast steel roll and also good wear resistance of cast iron roll. The matrix contains a small amount of uniform spherical (point-like) graphite, which gives the alloy graphite steel roll good anti-thermal cracking performance and excellent thermal stability, as well as higher bite friction coefficient, good toughness and wears resistance. In addition, its tensile strength is high with small variation in hardness.
