Allegheny Technologies Introduces Versatile ATI 425 Titanium Alloy.

Business Editors

PITTSBURGH--(BUSINESS WIRE)--Aug. 18, 2003

Allegheny Technologies Incorporated (NYSE:ATI) announces ATI(TM) 425 titanium, an innovative new titanium product that is an alternative to the most common high-strength titanium alloy and an addition to ATI's wide range of high-strength titanium alloys. ATI 425 titanium offers strength comparable to Ti-6Al-4V; yet, unlike Ti-6Al-4V titanium, ATI 425 titanium is both hot and cold workable. As a result, ATI 425 titanium can be produced in a variety of forms, including sheet, coil, strip, Precision Rolled Strip(R) product, plate, seamless tube and pipe as well as cast and engineered products.

"ATI 425 titanium is the result of our new product development and Coordinated Business Development initiatives," said Jim Murdy, Allegheny Technologies' president and chief executive officer. "We recognized that the market needed a high-strength, lightweight material that provides certain advantages compared to existing specialty materials. Because ATI 425 titanium is both hot and cold workable, we can provide nearly all required product forms to a variety of end-use markets using ATI's extensive array of finishing capabilities."

ATI 425 titanium is covered by ATI's issued patents and pending patent applications. Target markets for the proprietary ATI 425 titanium include aerospace, defense, industrial, medical and recreation in applications where high-strength, lightweight materials are required. In addition, the alloy's corrosion resistance to saltwater environments (similar to that of Ti-6Al-4V) makes it a candidate material in marine-related applications.

One of the key strengths of ATI 425 titanium is that it is comparatively easy to produce and form due to its workability during the production and forming processes. Tests have shown that ATI 425 titanium can be fabricated more easily than Ti-6Al-4V. Duplex annealed ATI 425 titanium plate exhibited good fracture toughness; cold rolled and annealed ATI 425 titanium sheet has been bent to radii of 2.5 times its thickness. ATI 425 titanium is also heat treatable and can be solution-treated and aged to higher strength levels. Initial results indicate that the alloy is weldable and that annealed welds are ductile.

Allegheny Technologies plans further development of ATI 425 titanium products for a wide variety of uses. For further information or to discuss potential applications, please contact Mr. Larry Martin, business development manager, ATI Wah Chang, at 541-924-6896.
