Abstract

PURPOSE:To obtain the titled roll showing excellent durability by forming said roll with the grain material alloy consisting of C, Si, Mn, P, S, Ni, Cr, Mo and Fe having the specific compsn. and contg. graphite in the specific areal ratio. CONSTITUTION:The outer layer material is at least formed with the grain material alloy contg., by weight, 2.8-4.0% C, 0.5-1.5% Si, 0.5-1.0% Mn, <=0.08% P, <=0.06% S, 3.0-5.0% Ni, 1.0-3.0% Cr, 1.5-5.0% Mo and the balance consisting substantially of Fe and contg., by areal%, 3-5% graphite in the structure, by which the roll for hot rolling having excellent wear resistance, roughness resistance and accident resistance is obtd.
