WEST CHESTER, Ohio, April 19, 2013

WEST CHESTER, Ohio, April 19, 2013 /PRNewswire/ --AK Steel (NYSE: AKS)
applauds the U.S. Department of Energy's (DOE) final ruling on efficiency
standards for electrical distribution transformers. The rule was published in
the Federal Register on April 18, 2013 following an extensive comment and
review process. It ensures that transformers in America will remain among the
most energy-efficient in the world, and that high-tech electrical steels will
continue to be a competitive material in the marketplace.

"As a global leader in the production of high-efficiency electrical steel
products, we are pleased with the Department of Energy's new standards," said
James L. Wainscott, Chairman, President and CEO of AK Steel. "The ruling is
good for America, and it leaves AK Steel well-positioned to meet the needs of
its electrical power distribution customers for years to come."

The DOE's new standards, which become effective in 2016, are not expected to
significantly impact the overall competitiveness of the company's
grain-oriented electrical steel (GOES) products used in electrical
distribution transformers. In fact, with respect to some types of
distribution transformers, the new standards have the potential to increase
the market for GOES.

AK Steel's grain-oriented electrical steels are some of the highest
value-added specialty products available in the steel industry. They are
iron-silicon alloys with specific magnetic properties necessary to produce
highly efficient and economical electrical transformers.
