Abstract

PURPOSE: To obtain a rolling roll material with enhanced toughness and thermal impact resistance by adding a restricted amount of Si and Nb in place of Co in the composition of a high-speed tool steel.
CONSTITUTION: This rolling roll material consists of, by wt., 1.2W1.6% C, 0.5W 2.5% Si, ≤0.6% Mn, 3.0W5.0% Cr, 3.0W5.0% Mo, 3.0W5.0% V, 1.0W2.5% W, 1.0W 2.5% Nb and the balance Fe with impurities. This composition is obtd. by reducing the Cr, Mo and W contents of steel and adding such a restricted amount of Si and Nb in place of conventionally added Co. By this steel composition the rolling roll material has high wear resistance, high toughness and superior thermal impact resistance.
