| titleOfInvention | Roll outer layer material, and composite roll for hot rolling |
| abstract | A rolled outer layer material for hot rolling, wherein the roll surface layer is excellent in fatigue resistance, fatigue damage and chipping are less likely to occur, and a composite roll for hot rolling. A fine carbide having a circle equivalent diameter of 3 to 30 탆 at a number of 500 to 2500 / mm & And the presence of coarse carbide having a circle equivalent diameter of 50 mu m or more is 20 pieces / mm < 2 > By mass of Cr, 4.0 to 6.5% of Cr, 4.0 to 6.5% of Mo, 4.0 to 6.5% of Cr, 0.2 to 1.0% of Si, 0.2 to 1.0% (Cr), Mo, and V (content (mass%) of each element), and more preferably, Preferably, the roll outer layer material is composed of a composition containing 0.001 to 0.05% of Al or 0.001 to 0.03% of REM, and the balance of Fe and unavoidable impurities. And an outer layer composed of the outer layer material. |
