Composition (%) & Hardness of BodyThe 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
