Abstract

PURPOSE: To obtain a roll with enhanced wear resistance, impact strength, mechanical workability, etc. for hot working a metal with a high m.p. by forming a roll part for rolling such a metal with a steel contg. a specified percentage of Cr, Mo, V, C, Mn and Ni.
CONSTITUTION: The rolling part of a three way roll or the like for rolling a metal with a high m.p. such as W or Mo is formed with a steel consisting of, by wt., 0.70W1.50% Cr, 0.20W0.50% Mo, ≤0.30% V, 0.50W0.80% C, 0.60W1.20% Mn, ≤3.00% Ni and the balance Fe with inevitable impurities. The material of this roll for working is restricted to that corresponding to SKT 1W6, and by this composition conditions such as thermal impact strength, mechanical strength, workability and manufacturing cost as a roll for hot working a metallic material with a high m.p. can be satisfied.
