Abstract
Rolling mill shear provided with at least one blade having characteristics of toughness and resistance to thermal shock typical of the family of tool steels for hot shearing and at the same time having sufficiently high characteristics of surface hardness and wear resistance, typical of tool steels for cold shearing. This shear is particularly suitable for carrying out, with greater efficiency and for a longer time, relative to the known shears, the shearing of sections or bars at a temperature between 150 and 800° C., downstream of the Quenching & Tempering heat treatment thereof.
