Allegheny Technologies Announces Titanium and Specialty Plate Facility Expansion

    PITTSBURGH--(BUSINESS WIRE)--Jan. 17, 2007--Allegheny Technologies
Incorporated (NYSE:ATI) announced that its Board of Directors has
approved the expansion of the Company's titanium and specialty plate
facility located in Washington, PA. The purpose of the capital project
is to meet growing demand from the aerospace and defense, chemical
process industry, oil and gas, and electrical energy markets. ATI
expects this investment to be approximately $60 million with
completion planned for the second quarter 2008.

    "Expanding our titanium and specialty plate capabilities balances
our production flow with our previously announced titanium sponge,
titanium melt, and nickel-based alloy melt growth projects," said
Patrick Hassey, Chairman, President and Chief Executive Officer of
Allegheny Technologies. "The expected return on this self-funded
growth investment is very attractive.

    "ATI's long-term titanium supply agreement in the aerospace
airframe market and projected growth in demand from the defense market
and from markets vital to building and rebuilding the global
infrastructure make this project a necessity to achieving our
strategic growth objectives. Together, these markets provide exciting
growth prospects for our titanium and titanium alloy, duplex alloy,
superaustenitic alloy, nickel alloy, zirconium alloy, and stainless
steel plate products."

    The titanium and specialty plate capital project includes
increasing reheat furnace, annealing, and flattening capacity at ATI's
existing plate mill. In addition, ATI's plate size capabilities are
being expanded and significant productivity improvements are being
made.

    In addition to titanium and titanium alloys, ATI's specialty plate
products include duplex alloys, superaustenitic alloys, nickel-based
alloys, zirconium alloys, armor plate, and common austenitic stainless
grades. Plate is a flat-rolled mill product that is 3/16 inch (4.76
mm) thick, or greater, and over 10 inches (254 mm) wide.

    This news release contains forward-looking statements that are
based on management's current expectations and include known and
unknown risks, uncertainties and other factors, many of which we are
unable to predict or control, that may cause our actual results,
performance or achievements to materially differ from those expressed
or implied in the forward-looking statements. Important factors that
could cause actual results to differ materially from those in the
forward-looking statements include: (a) material adverse changes in
economic or industry conditions generally, including global supply and
demand conditions and prices for our specialty metals; (b) material
adverse changes in the markets we serve, including the aerospace and
defense, chemical process industry, oil and gas, electrical energy,
construction and mining, automotive, and other markets; (c) our
inability to achieve the level of cost savings, productivity
improvements, synergies, growth or other benefits anticipated by
management, including those anticipated from strategic investments and
the integration of acquired businesses, whether due to significant
increases in energy, raw materials or employee benefits costs, or
other factors; (d) volatility of prices and availability of supply of
the raw materials that are critical to the manufacture of our
products; and (e) other risk factors summarized in our Annual Report
on Form 10-K for the year ended December 31, 2005, and in other
reports filed with the Securities and Exchange Commission. We assume
no duty to update our forward-looking statements.
