Product Details


Spheroidal graphite cast iron roll ring

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.

Mechanical properties
Hardness of shell HSD45-80
Hardness of core HSD32-55
Tensile Strength of core ≥320MPa
