Product Description

Graphite cast steel roll

Description
The graphitic steel rolls hae a metallographic structure consisting of carbides and a small amount of graphite in he pearlitic matrix. The rolls of this material has tensile strength and better resistance to  thermal cracking than adamite rolls of the same hardness, and the wear resisitance of which is better than the cast steel rolls.
