Zusammenfassung:PURPOSE: To produce a high heat crack resistant roll material for hot rolling highly adaptive to a hot rolling roll excellent in heat crack resistance in a high temp. region and furthermore excellent in wear resistance and seizing resistance. CONSTITUTION: This high heat crack resistant roll material for hot rolling is the one contg., by weight, 1.0 to 2.4% C, 0.3 to 2.0% Si, 0.1 to 2.0% Mn, 6.0 to 15.0% Cr, 4.0 to 10.0% V, 3.0 to 8.0% Co, and the balance Fe with inevitable impurities. Furthermore, in the case of improving the same characteristics, 0.01 to 2.0% Ti and Zr may be incorporated therein.
