National Highway Traffic Safety Administration report identifies
cost-effective mass reduction with advanced high-strength steels

DETROIT, Dec. 5, 2012

DETROIT, Dec. 5, 2012 /PRNewswire/ --A recently published National Highway
Traffic Safety Administration (NHTSA) report entitled Mass Reduction for
Light-Duty Vehicles for Model Years 2017-2025 prepared by EDAG, Inc., George
Washington University and Electricore, Inc. examined mid-size body, chassis
and interior vehicle systems and determined that basic lightweighting costs
$0.46 per pound of weight saved ($1.02 per kilogram) using advanced
high-strength steels (AHSS), compared to $1.55 per pound ($3.41 per kilogram)
using aluminum. This report is the latest to confirm that AHSS remain the most
affordable mass reduction solution for North American vehicles.

"Cost models have traditionally associated a significant cost penalty with
alternative materials and this NHTSA report confirms this while demonstrating
advanced high-strength steels provide significant mass reduction at the lowest
possible cost," Lawrence W. Kavanagh, president, Steel Market Development
Institute, a business unit of the American Iron and Steel Institute, said.
"This is significant, as automakers have the challenging task of developing
affordable vehicles that meet new and tightening regulations."

In addition to its cost advantage, steel's ability to provide unparalleled
crash performance for safety was also confirmed in this report. George
Washington University verified the excellent crash performance of the
lightweight vehicle design in simulated New Car Assessment Program, Frontal,
Lateral Moving Deformable Barrier, and Lateral Pole tests, along with the
International Institute for Highway Safety's Roof, and Frontal Offset
tests.

"This extraordinary safety performance is due to steel's unique ability to
reinvent itself by continually expanding the range of properties and
performance available to the auto design engineer," Kavanagh said. "There is
no other material that can provide the automotive industry with the complete
package necessary to meet CAFE regulations. As a result, steel will remain the
preferred material as it enables carmakers to enhance mass reduction,
manufacturability and safety at the lowest cost of any material."

The American Iron and Steel Institute (AISI) serves as the voice of the North
American steel industry in the public policy arena and advances the case for
steel in the marketplace as the preferred material of choice. AISI also plays
a lead role in the development and application of new steels and steelmaking
technology. AISI is comprised of 25 member companies, including integrated and
electric furnace steelmakers, and 125 associate members who are suppliers to
or customers of the steel industry. AISI's member companies represent over
three quarters of both U.S. and North American steel capacity.

The Steel Market Development Institute (SMDI) grows and maintains the use of
steel through strategies that promote cost-effective solutions in the
automotive, construction and container markets, as well as for new growth
opportunities in emerging steel markets. For more news or information, visit
