Product Description

Product description

High Speed Steel Mill Roll (HSS) Rolls for Bar Mill

 

1. Chemical Composition (%) & Hardness of Body

The shell of HSS Rolls is a high carbon alloy steel containing Cr,Mo,W,V and Nb.The Microstructure consists of complex carbides embedded in a tempered martensitic matrix.Control of the carbon and a complex heat treatment allows the optimization of wear resistance,thermal fatigue resistance and oxide film formation,whilst maintaining low residual stress values.
