    Another award for hot stamped, single piece door ring

ArcelorMittal takes home “Innovation – Award” for its hot-stamped, single-piece door ring

ArcelorMittal proudly accepted the "Safety" award at CLEPA's annual awards for Innovation during a "Dinner for Winner" ceremony on 8 October in Brussels.

Brussels, 8th ctober 2014 – This award recognized ArcelorMittal’s role in introducing the industry’s first single-piece, hot-stamped, laser-welded door ring found in the 2014 Acura MDX, manufactured by Honda. The Door ring concept brings the safety part of the body-in-white to a whole new level and is an affordable way to save weight.

Clepa, the European Association of Automotive Suppliers held its annual Award Ceremony in Brussels on October 7th 2014. During this "Dinner for Winner", the hot stamped door ring, presented by ArcelorMittal, won the 1st place in the ‘Safety’ Category. 2nd place winners were tied, with prestigious names such as Bosch and Continental.

Keen interest from various carmakers

"The door ring is an innovative concept improving vehicle safety, with top ratings in the ever more demanding crash tests, while allowing significant weight reduction and an easier assembly on the vehicle… at a competitive cost. It has been implemented thanks to a close cooperation between different ArcelorMittal units, in Europe and North America. We are now seeing a keen interest from many OEMs around the World and are already actively working on the industrialization on the second, mass-produced vehicle," commented Philippe Baudon, who accepted the award on behalf of ArcelorMittal and its Tailored Blanks division.

Global cooperation key

ArcelorMittal and ArcelorMittal Tailored Blanks worked closely with Honda and Magna’s Cosma International, a tier-one hot stamper, to develop the door ring. The door ring enhances the safety performance of the Acura MDX to meet today’s stringent roof crush and side impact standards, as well as the demanding new small overlap front crash test. In addition to enhanced safety, the MDX achieved weight reduction and performance targets, without adding additional cost to the consumer.

This new award, following the PACE Award received in May and American Metal Market's "Best Innovation" award received in June 2014, confirms the excellence of ArcelorMittal Steel Solutions for Automotive and its credibility in the Automotive world.

Lighter, faster, stronger
The ultimate result after hot-stamping is a lighter, stronger door ring, which serves as a critical component of the MDX body structure and replaces the conventional multi-piece spot weld design. The vehicle’s performance in the new offset frontal crash test – where a car strikes an object with only 25 percent of the vehicle – was textbook. The area of impact collapsed as it should, stopping at the door ring, which allowed the door to easily open and close, and the passenger to safely exit.

Safety first
The door ring creates an industry standard that global automakers can easily adopt. Globally, ArcelorMittal is currently supplying or launching ablated Usibor® or Ductibor® solutions for seven major automakers, demonstrating that the ablation process is a key component of ArcelorMittal’s automotive growth strategy.

It is expected that the North American automotive customers alone will adopt more than four million, hot-stamped, laser-welded blanks during the next two years. In Europe too, various carmakers are studying the door ring for their next models.
