Abstract

The invention is a steel, advantageously but not exclusively for making rolling mills and/or continuous casting rolls, comprising a variable percentage - in weight - alloyed with iron Fe: C from 0.48 % to 0.60%, Mn from 0.45% to 0.60%, Si from 0.30% to 0.60%, Ni from 0.40% to 0.60%, Cr from 1.80% to 2.50%, Mo from 0.80% to 1.10%, V from 0.30% to 0.50%, W from 0.30% to 0.70%. The invention also concerns a heat treatment, a rolling mill and a shell for rolling mills.
