LEIPSIC, Ohio, May 13, 2013 /PRNewswire/ -- Today, United States Steel
Corporation (NYSE: X) and Kobe Steel, Ltd., of Japan formally commissioned the
new Continuous Annealing Line at their joint venture PRO-TEC Coating Company.
PRO-TEC will now process some of the strongest and most formable grades of
steel in North America. These new grades will assist automotive manufacturers
in reaching the 2025 Corporate Average Fuel Economy (CAFE) standards of 54.5
miles per gallon for their passenger vehicle fleets and maintain the rigorous
safety standards consumers demand.

Through cutting-edge heat treat and quench technology, the 500,000-ton PRO-TEC
Continuous Annealing Line will produce the next generation of Advanced High
Strength Steels (AHSS) and Ultra High Strength Steels (UHSS) from 590
mega-pascal and higher. These new grades of steel have unmatched metallurgical
properties -- superior strength, flatness and formability previously
unavailable at these strength levels. These steels support our customers by
offering critical design solutions as automotive companies reduce the weight
of component materials in their line to improve fuel economy while continuing
to enhance strength to improve passenger safety. These properties, coupled
with steel's inherent recyclability and overall environmental performance,
make steel the material of choice for automotive manufacturers.

"The investment in this Continuous Annealing Line represents more than just
the future of this facility – it also represents the future for automotive
steel products and the applications in which they are used," said U. S. Steel
Chairman and CEO John Surma. "U. S. Steel and Kobe Steel saw an opportunity
for our PRO-TEC joint venture to help our automotive customers overcome the
challenges associated with the 54.5 mpg regulation, and the products processed
at PRO-TEC's new Continuous Annealing Line will offer our customers
affordable, highly advanced options that will position them for ongoing

Industry wide, in the last 10 years, the use of high-strength steels has
doubled in number, and as a result are the fastest growing materials in the
car. These newly formulated grades reduce vehicle weight without sacrificing
safety and importantly, affordability.

The commissioning event is a culmination of a $400 million capital investment
by the partners into PRO-TEC. Announced in late 2010, the investment created
500 temporary construction jobs as well as 80 full-time jobs. PRO-TEC has
served the automotive industry's need for high-quality, value-added steel
products for 20 years. Dignitaries attending the event included United States
Steel Chairman and CEO John P. Surma; Kobe Steel President and CEO Hiroya
Kawasaki; PRO-TEC Coating Company President Bryan Vaughn; representatives from
automotive manufacturers; and state and local elected officials.
