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.
