Advanced high strength steels to help automakers meet fuel-efficiency standards

As a result of a new research, global steelmaker ArcelorMittal has collected new evidence further demonstrating the potential of advanced steel products in helping automakers meet the US fuel-efficiency standards set to be reached by 2025.
 
According to ArcelorMittal, based on US Environmental Protection Agency (EPA) and National Highway Traffic Safety Administration (NHTSA) modeling, advanced high strength steels (AHSS) can deliver vehicle ‘lightweighting' benefits at a lower cost to the consumer and with less environmental impact than alternative solutions such as aluminum, magnesium or carbon fiber.
 
ArcelorMittal indicated that AHSS can provide a 7.2 percent fuel economy improvement at little or no cost to the original equipment manufacturer, which is up to six times more cost effective than aluminum. Besides, an aluminum car requires twice the amount of CO2 to manufacture than a car made of AHSS, since the body structure accounts for about one third of the curb weight of a typical vehicle. ArcelorMittal supplies about 17 percent of the world's automotive market, with a strong presence in North America, Europe, South America and South Africa and an emerging presence in China.
