Heat treatment and mechanical properties of heavy forgings from A694-F60 steel

Abstract

The production of heavy steel forgings of micro-alloyed steels gives the possibility to obtain advantages associated with the benefit of the application of micro-alloying elements and thermomechanical treatments for improving the mechanical properties of forgings to level by sheets, strips and tubes. The paper presents the influence of quenching temperature on the mechanical properties and microstructure of F60 steel according to ASTM A694. The verification of the influence of quenching temperature contributes to an optimization of the method of micro-alloyed steel heat treatment. The steel’s microstructure and mechanical properties after quenching constitute the initial and basic criteria to achieve the required mechanical properties after a properly chosen tempering temperature.
