Abstract

Provided is a roll surface layer material for hot rolling produced by centrifugal casting the roll surface layer material including a roll skin layer that has excellent fatigue resistance. The roll surface layer material produced by centrifugal casting has a composition which contains in terms of mass% 2.3 2.9% C 0.2 0.8% Si 0.2 1.0% Mn 5.0 7.5% Cr 4.4 6.5% Mo 5.3 7.0% V 0.6 1.5% Nb and 0.1 4.0% Co so that 14.0=(Mo+1.7V)=17.0 (wherein Mo and V are the contents of the elements (mass%)) is satisfied and which further contains 0.001 0.03% Al and/or 0.001 0.03% REM. The material contains carbides in an amount of 13 40% in terms of areal proportion. Due to this configuration the skin layer has significantly improved fatigue resistance. A shaft material is fusion bonded to and integrated with this roll surface layer material to produce a composite roll. This composite roll which is produced through centrifugal casting is excellent in terms of the fatigue resistance of the skin layer and is suitable for use as a roll for hot finish rolling.
