Product Description

HiCr Iron and HiCr steel rolls are having high Cr carbide content with a tempered martensitic bainitic matrix in the working 
shell. Centrifugally cast compound HiCr rolls are made of highly wear and fire crack resistant shell with nodular cast iron core. They provide very high thermal shock resistance, longer pass life and very good surface finish.

HiCr Iron rolls are ideal for roughing work rolls of HSM, plate mill work rolls, skin pass and cold rolling work rolls. Durability during longer run time, resistance to fire cracking and banding are advantages. 

Hardness property is stable during whole life of these rolls. Hence, re-hardening or reconditioning is not required.HiCr Steel rolls are used for reversing and continuous HSM roughing rolls, steckel mill rolls and plate mill rolls. Superior mechanical strength of HiCr steel rolls make them ideal for heavy duty rolling conditions.

Heat treatment at high temperatures modify the structure to obtain optimum mechanical and physical 
properties
