In response to the
article, "Aluminum Industry Girds for Auto Battle,"
(amm.com, Sept. 19) the steel industry would like to
clarify several points.
steels (AHSS)which offer weight reduction on par with
aluminum and superior cost and environmental
performanceare currently in production. In fact, AHSS
make up nearly 15 percent of North American vehicles on the
road today, are rapidly growing and help automotive
manufacturers meet mandated fuel economy requirements.
Not only do AHSS
compete in applications with extruded aluminum, the steel
industry is working with automakers to maximize their use of
AHSS to find the most cost-effective solutions to meet new fuel
economy (54.5 miles per gallon by 2025) requirements.
There are several
examples of AHSS technologies that are ready for production or
on the road today. One in particular is the front lower control
arm (a suspension application) that is the same weight as the
aluminum version at one-third less cost.
Best of all, the new
steel designs achieve such weight and cost savings at a lower
total life-cycle carbon footprint than if other lightweight
materials are used. In addition, they can be implemented
without substantial stamping plant or body shop investment
compared with the more radical changes needed to use other
