             Report of Independent Registered Public Accounting Firm

Allegheny Technologies Incorporated

We have audited the accompanying statements of net assets available for benefits
of the 401(k) Savings Account Plan for Employees of the Washington Plate Plant
as of December 31, 2003 and 2002, and the related statements of changes in net
assets available for benefits for the years then ended. These financial
statements are the responsibility of the Plan's management. Our responsibility
is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan at
December 31, 2003 and 2002, and the changes in its net assets available for
benefits for the years then ended, in conformity with U.S. generally accepted
accounting principles.

Our audits were performed for the purpose of forming an opinion on the financial
statements taken as a whole. The accompanying supplemental schedule of assets
(held at end of year) as of December 31, 2003 is presented for purposes of
additional analysis and is not a required part of the financial statements but
is supplementary information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974. The supplemental schedule is the responsibility of the
Plan's management. The supplemental schedule has been subjected to the auditing
procedures applied in our audits of the financial statements and, in our
opinion, is fairly stated in all material respects in relation to the financial
statements taken as a whole.

                     Years ended December 31, 2003 and 2002

1. SIGNIFICANT ACCOUNTING POLICIES

Investments are valued as follows:

      Bank and insurance investment contracts with varying contract rates and
      maturity dates are stated at contract value.

      Although it is management's intention to hold the investment contracts in
      the Fixed Income Master Trust until maturity, certain investment contracts
      provide for adjustments to contract value for withdrawals made prior to
      maturity.

      All other investments are stated at their net asset value, based on the
      quoted market prices of the securities held in such funds on applicable
      exchanges.

The preparation of financial statements in conformity with U.S. generally
accepted accounting principles requires management to make estimates that affect
the amounts reported in the financial statements and accompanying notes. Actual
results could differ from those estimates.

2. DESCRIPTION OF THE PLAN

The 401(k) Savings Account Plan for Employees of the Washington Plate Plant (the
Plan) is a defined contribution plan and is subject to the provisions of the
Employee Retirement Income Security Act of 1974 (ERISA).

The purpose of the Plan is to encourage thrift and to assist represented
employees of the Washington Plate facility of Allegheny Ludlum Corporation (the
Company) in accumulating a fund to supplement retirement income by allowing
eligible employees to make tax-deferred contributions to the Plan. Allegheny
Ludlum Corporation is a wholly owned subsidiary of Allegheny Technologies
Incorporated (ATI, the Plan Sponsor). The Plan allows employees to contribute a
portion of eligible wages each pay period through payroll deductions subject to
Internal Revenue Code limitations. In addition, the employee's annual pretax
profit sharing award and pretax Longevity Incentive Payment Plan award may be
contributed at the employee's discretion. The Company contributes $0.50 for each
hour worked per eligible represented employee. Unless otherwise specified by the
participant, all contributions are made to the Fixed Income Fund. Such
contributions are made only from current income or accumulated earnings of the
Company. The Plan allows participants to direct their contributions, and
contributions made on their behalf, to any of the investment alternatives.
Unless otherwise specified by the participant, employer contributions are made
to the Fixed Income Master Trust.

                                                                               4

                          of the Washington Plate Plant

                    Notes to Financial Statements (continued)

2. DESCRIPTION OF THE PLAN (CONTINUED)

Separate accounts are maintained by the Plan Sponsor for each participating
employee. Trustee fees and asset management fees charged by the Plan's trustee,
Mellon Bank, N.A., for the administration of all funds are charged against net
assets available for benefits of the respective fund. Certain other expenses of
administering the Plan are paid by the Plan Sponsor.

Participants may make "in-service" and hardship withdrawals as outlined in the
plan document.

Active employees can borrow up to 50% of their vested account balances minus any
outstanding loans. The loan amounts are further limited to a minimum of $500 and
a maximum of $50,000, and an employee can obtain no more than three loans at one
time. Interest rates are determined based on commercially accepted criteria, and
payment schedules vary based on the type of the loan. General purpose loans are
repaid over 6 to 60 months, and primary residence loans are repaid over periods
up to 180 months. Payments are made by payroll deductions.

Further information about the Plan, including eligibility, vesting,
contributions, and withdrawals, is contained in the plan documents, summary plan
description, and related contracts. These documents are available from the Plan
Sponsor.

3. INVESTMENTS (CONTINUED)

Certain of the Plan's investments are in the Allegheny Technologies Incorporated
Savings Plan Trust, which has three subsidiary Master Trusts: the Allegheny
Technologies Disciplined Stock Fund Master Trust, the Alliance Equity Master
Trust, and the Fixed Income Master Trust, which are institutional separate
accounts valued on a unitized trust basis (collectively, the Master Trust). The
Master Trust was established for the investment of assets of the Plan, and
several other ATI sponsored retirement plans. Each participating retirement plan
has an undivided interest in the Master Trust. At December 31, 2003 and 2002,

Allegheny Technologies Disciplined Stock Fund Master Trust, and the Fixed Income
Master Trust was as follows:

The Fixed Income Fund (the Fund) invests in guaranteed investment contracts
(GICs) and actively managed structured or synthetic investment contracts (SICs).
The GICs are promises by a bank or insurance company to repay principal plus a
fixed rate of return through contract maturity. SICs differ from GICs in that
there are specific assets supporting the SICs, and these assets are owned by the
Master Trust. The bank or insurance company issues a wrapper contract that
allows participant-directed transactions to be made at contract value. The
assets supporting the SICs are comprised of government agency bonds, corporate
bonds, asset-backed securities (ABOs) and collateralized mortgage obligations
(CMOs) with fair values of $107,926,162 and $88,750,762 at December 31, 2003 and
2002, respectively.

Interest crediting rates on the GICs in the Fund are determined at the time of
purchase. Interest crediting rates on the SICs are either: (1) set at the time
of purchase for a fixed term and crediting rate; (2) set at the time of purchase
for a fixed term and variable crediting rate, or (3) set at the time of purchase
and reset monthly within a "constant duration." A constant duration contract may
specify a duration of 2.5 years and the crediting rate is adjusted monthly based
upon quarterly rebalancing of eligible 2.5 year duration investment instruments
at the time of each resetting; in effect the contract never matures. At December
31, 2003 and 2002, the interest crediting rates for GICs and Fixed Maturity SICs
ranged from 3.58% to 8.02% and 3.27% to 8.05%, respectively.

For the years ended December 31, 2003 and 2002, the average annual yield for the
investment contracts in the Fund was 5.31% and 5.74%, respectively. Fair value
of the GICs was estimated by discounting the weighted average of the Fund's cash
flows at the then-current, interest-crediting rate for a comparable maturity
investment contract. Fair value for the SICs was estimated based on the fair
value of each contract's supporting assets at December 31, 2003 and 2002.

                                                                               8

Interest, realized and unrealized gains and losses, and management fees from the
master trusts are included in the net gain (loss) from interest in Allegheny
Technologies Incorporated Savings Plan Trust on the statements of changes in net
assets available for benefits.

4. INCOME TAX STATUS

The Plan has received a determination letter from the Internal Revenue Service
dated July 12, 2003, stating that the Plan is qualified under Section 401(a) of
the Internal Revenue Code (the Code) and, therefore, the related trust is exempt
from taxation. The determination letter does not include Plan amendments
subsequent to December 31, 2001. Once qualified, the Plan is required to operate
in conformity with the Code to maintain its qualification. The plan
administrator believes the Plan is being operated in compliance with the
applicable requirements of the Code and, therefore, believes the Plan, as
amended, is qualified and the related trust is tax-exempt.



                                                                              10

5. PARTIES-IN-INTEREST

Dreyfus Corporation is the manager of the Dreyfus Mutual Funds that are offered
as investment options under this Plan. Dreyfus Service Corporation is the funds'
distributor. Dreyfus Corporation and Dreyfus Service Corporation are both wholly
owned subsidiaries of Mellon Financial Corporation. Mellon Financial Corporation
also owns Mellon Bank, N.A., the trustee for this Plan. Therefore, transactions
with these entities qualify as party-in-interest transactions.

6. PLAN TERMINATION

Although it has not expressed any intent to do so, the Company has the right
under the Plan to discontinue its contributions at any time and to terminate the
Plan subject to the provisions of ERISA.

7. RISKS AND UNCERTAINTIES

The Plan invests in various investment securities. Investment securities are
exposed to various risk such as interest rate, market and credit risks. Due to
the level of risk associated with certain investment securities, it is at least
reasonably possible that changes in the values of investment securities will
occur in the near term and that such changes could materially affect
participants' account balances and the amounts reported in the statements of net
assets available for benefits.
