To reduce the weight of the 2017 Chrysler Pacifica while meeting or exceeding crash test requirements and minimizing costs to the consumer, ArcelorMittal (Chicago, IL) and ArcelorMittal Tailored Blanks began co-engineering work with FCA US LLC in 2012 to identify applications that would meet all objectives. Using ArcelorMittal’s patented laser ablation process, the company combined two high-strength steel grades—Usibor, a hot stamping grade that supports weight reduction in advanced shapes that require higher tensile strength, and Ductibor, an energy-absorbing grade designed specifically to complement Usibor in hot-stamping applications and offer ductility—to better manage the crash energies. Together, the partners identified the side structure of the vehicle’s body-in-white, specifically the door ring and B-pillar, as the area of most opportunity for weight reduction and improved safety performance. The team came to an agreement on one central concept, what ArcelorMittal claims is the world’s first five-piece hot-stamped laser-welded door ring and B-pillar ( Visit Booth 3806 at SAE WCX17.
