Jan. 18, 2007 — Allegheny Technologies Inc.’s Board of Directors has approved expansion of the company’s Washington, Pa., titanium and specialty plate facility.

The project includes increasing the reheat furnace, annealing, and flattening capacity at ATI’s existing plate mill. ATI’s plate size capabilities will be expanded, and significant productivity improvements are also being made.

The capital project is intended to help ATI meet growing demand from the aerospace and defense, chemical process industry, oil and gas, and electrical energy markets. ATI expects the 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, Allegheny Technologies’ Chairman, President and CEO. “The expected return on this self-funded growth investment is very attractive.

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.

“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.”

Allegheny Technologies is one of the largest and most diversified specialty metals producers in the world. ATI’s major markets are aerospace and defense, chemical process industry/oil and gas, electrical energy, medical, automotive, food equipment and appliance, machine and cutting tools, and construction and mining. Products include titanium and titanium alloys, nickel-based alloys and superalloys, stainless and specialty steels, zirconium, hafnium, and niobium, tungsten materials, grain-oriented silicon electrical steel and tool steels, and forgings and castings.
