Abstract
The piercing and trimming using laser deteriorate productivity of the hot stamping process and increase the cost of hot-stamped parts. In this study, the possibility if the laser cutting can be substituted by hot piercing and trimming is discussed from a viewpoint of the sensitivity against the delayed fracture. The stretch forming and hole expanding in hot stamping are also investigated.
