The steels for quenching and tempering are used for components subjected to high mechanical stress, determined by bending forces, tensile strength, torsion, compression and cutting.
The degree of static stress resistance depends on the one hand on strength properties of steel grades (such as hardness, tensile and yield strength); on the other, it depends on toughness in order to avoid brittle fractures.
Quenching and tempering, which is a heat treatment process that is normally carried out on the final finishing stage of pieces, determines high mechanical properties.
Interacciai S.p.a trades and deals with Cold Worked, Hot Rolled and Forged Steels for Quenching and Tempering providing customized supply solutions based on specifications and other specific requirements in order to meet every customer’s need in terms of grades and profiles.
