           ALLEGHENY TECHNOLOGIES COMPLETES ACQUISITION OF J&L ASSETS

Pittsburgh, PA - June 1, 2004 - Allegheny Technologies Incorporated (NYSE:ATI)
announced today that it has completed the acquisition of certain assets of J&L
Specialty Steel, LLC (J&L). The closing of the acquisition followed ratification
on May 28, 2004, of a new progressive labor agreement by United Steelworkers of
America (USWA) represented employees at ATI Allegheny Ludlum and at the former
J&L facilities.

"Our new labor agreement combined with our acquisition of these assets go a long
way to `fix' our stainless steel business," said Pat Hassey, Chairman, President
and Chief Executive Officer of Allegheny Technologies. "We believe we have
created a stronger Allegheny Ludlum. Allegheny Ludlum now has a more competitive
cost structure. It has modern facilities and a diversified product mix and is
capable of shipping in excess of 700,000 tons of flat-rolled products annually.
Allegheny Ludlum is well positioned to sustain and enhance its position as one
of the premier flat-rolled specialty metals companies in the world.

"Implementation of our integration plan begins today at key facilities in
Midland, PA and Louisville, OH. We welcome the former J&L employees, who will
number approximately 400 after a short transition period. This transaction
maintains J&L's key capacity in the U.S. flat-rolled stainless steel market. We
expect these facilities to have a real impact. They complement and enhance
Allegheny Ludlum's manufacturing process.

"The USWA leadership and its represented employees recognized what needed to be
done to make Allegheny Ludlum more cost competitive on a global basis. Working
together, we were able to construct an agreement that improves Allegheny
Ludlum's cost structure, while saving jobs and providing a good compensation
package.

"Highlighting the labor agreement is a new work environment. It facilitates
implementation of the ATI Business System. New flexible work rules enable
efficient modern practices and reduce the number of production and maintenance
job grades to 5 from 33. Employees are given broader responsibility and have the
opportunity to become more engaged in the business. We believe this modern work
environment secures a strong future for Allegheny Ludlum and its employees."

Because of workforce restructuring, one-time Transition Assistance Payments
(TAPS) incentives will be offered by ATI to approximately 775 hourly employees
who decide to retire over the next 2 1/2 years. The agreement expires June 30,
2007, and replaces existing

labor agreements at Allegheny Ludlum and at the former J&L Midland, PA and
Louisville, OH facilities.
