Flow Characteristics of New Steel Grades Dedicated to Hot Stamping

Article Preview

Abstract:

The reduction of the maximum temperature is one of the main goals in the research activities dedicated to hot sheet stamping, thanks to the benefits it can produce in terms of energy consumption and die wear decrease. New steel grades are being expressly developed with the aim of reducing the austenitization temperature without losing the mechanical characteristics and the formability shown by the conventional Usibor 1500P™. In the present work, the flow behavior of four new steel grades is investigated by means of hot tensile tests at varying thermo-mechanical conditions. Results are presented and discussed in terms of obtained mechanical and ductility characteristics.
