Product Description
We can provide the full ranges of rolls for the Bar & Wire mills, covering roughing rolls, intermediate rolls and finishing rolls.
High speed steel roll
Properties
The shell 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.
Chemical Analysis
Physical Properties
Microstructure
Tempered martensite + small percentage bainite + carbide
Application
Work rolls for roughing stands and front finishing stands of strip mill, work rolls for cold strip mill
