Centrifugal Casting High Speed Steel Roll and Ring for Rolling Mill


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.

Mechanical Properties Centrifugal
Hardness of shell HSD75-85
Hardness of neck HSD35-48
Tensile Strength of Core ≥450Mpa
