The reduction of the maximum heating temperature is one of the main goals in the research activities dedicated to hot stamping, to reduce energy consumption and decrease die wear. 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 1500PTM. 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, ductility and fracture characteristics.

Abstract
The reduction of the maximum heating temperature is one of the main goals in the research activities dedicated to hot stamping, to reduce energy consumption and decrease die wear. 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 1500PTM. 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, ductility and fracture characteristics.Pubblicazioni consigliate
