                          INDEPENDENT AUDITORS' REPORT


The Benefits Committee
Quanex Corporation
Houston, Texas

Re: Quanex Corporation 401(k) Savings Plan

We have audited the accompanying statements of net assets available for benefits
of the Quanex Corporation 401(k) Savings Plan ("the Plan") as of December 31,
2001 and 2000, 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 auditing standards generally accepted
in the United States of America. 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, such financial statements present fairly, in all material
respects, the net assets available for benefits of the Plan as of December 31,
2001 and 2000, and the changes in net assets available for benefits for the
years then ended in conformity with accounting principles generally accepted in
the United States of America.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The accompanying supplemental schedule of
investments as of December 31, 2001 is presented for the purpose of additional
analysis and is not a required part of the basic 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. This supplemental schedule has been subjected to the auditing
procedures applied in our audits of the basic financial statements and, in our
opinion, are fairly stated in all material respects when considered in relation
to the basic financial statements taken as a whole.

                               401(k) SAVINGS PLAN

                          NOTES TO FINANCIAL STATEMENTS
                     YEARS ENDED DECEMBER 31, 2001 AND 2000


A.       DESCRIPTION OF THE PLAN

         The following description of the Quanex Corporation 401(k) Savings Plan
         (the "Plan"), formerly the Nichols 401(k) Savings Plan, provides only
         general information. Participants should refer to the Plan document for
         more complete information.

         (1)      General. The Plan, sponsored by Quanex Corporation (the
                  "Company"), was established on October 1, 1987, and was
                  amended and restated in its entirety effective January 1,
                  1998. The Plan is a defined contribution plan that is subject
                  to the provisions of the Employee Retirement Income Security
                  Act of 1974 ("ERISA"). It covers substantially all salaried
                  and non-union hourly employees at the Nichols Aluminum
                  divisions and Engineered Products divisions, employees of
                  Temroc Metals, Inc., and bargaining unit employees at the
                  Lincolnshire, Illinois plant. The assets of the Plan are held
                  in trust by Fidelity Management Trust Company ("Fidelity" or
                  the "Trustee"). The Benefits Committee (the "Committee"),
                  appointed by the Company's Board of Directors, serves as the
                  Plan administrator.

                  Effective February 14, 2000, the employees of Nichols
                  Aluminum - Golden, Inc. became participants in the Plan.
                  Effective June 1, 2000, the employees of Imperial Products,
                  Inc. became participants in the Plan. Effective July 1, 2001,
                  the employees of Temroc Metals, Inc. became participants in
                  the Plan.

         (2)      Contributions. Beginning January 1, 2002, participants may
                  elect to contribute up to 50% of compensation (15% before
                  January 1, 2002) as defined by the Plan agreement. The
                  Bargaining unit employees at the Lincolnshire, Illinois plant
                  are limited to a 15% contribution of compensation. The Company
                  makes contributions on behalf of employees who have at least
                  one year of service. The Company contribution is based on
                  Company profits and is calculated based on a percentage of the
                  employee's compensation.

         (3)      Participant Accounts. Each participant's account is credited
                  with the participant's contribution, the employer's
                  contribution, and an allocation of investment income.
                  Investment income allocations are based on individual
                  participant account balances as of the end of the period in
                  which the income is earned.

         (4)      Vesting. Participants are immediately vested in their
                  voluntary contributions and earnings thereon. Vesting in the
                  employer contribution is based on years of credited service. A
                  participant is 20% vested for each year of credited service
                  and fully vested after five years. If a participant terminates
                  employment prior to becoming fully vested, the nonvested
                  portion of the employer contributions are immediately
                  forfeited by the participant and utilized to reduce future
                  employer contributions.

         (5)      Payment of Benefits. The Plan is intended for long-term
                  savings but provides for early withdrawals and loan
                  arrangements under certain conditions. Upon termination of
                  service, a participant may elect to receive a cash lump-sum
                  distribution equal to the amount of vested benefits in his or
                  her account. Terminated participants with account balances of
                  less than $5,000 will automatically receive a lump sum
                  distribution.

         (6)      Loans. Loans may be granted to a participant of the Plan at
                  the Committee's discretion. Loan terms range up to five years
                  or seven years if used for the purchase of a primary
                  residence. The loans bear a reasonable rate of interest
                  established by the Committee. Interest on the loan is
                  allocated to the borrower's participant account.





B.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         (1)      Accounting Basis. The financial statements of the Plan are
                  prepared on the accrual basis of accounting in accordance with
                  generally accepted accounting principles.

         (2)      Investment Valuation. The Plan recognizes net appreciation or
                  depreciation in the fair value of its investments. Investments
                  are reflected at fair value in the financial statements. Fair
                  value of mutual fund assets is determined using a quoted net
                  asset value. Fair value for Quanex Corporation common stock,
                  which is listed on the New York Stock Exchange, is determined
                  by using the last recorded sales price. The recorded value of
                  the common/commingled trust is at face value, which is fair
                  value.

         (3)      Use of Estimates. The preparation of financial statements in
                  conformity with generally accepted accounting principles
                  requires management to make estimates and assumptions that
                  affect the reported amounts of assets and liabilities and
                  changes therein and disclosure of contingent assets and
                  liabilities. Actual results could differ from these estimates.

         (4)      Administrative Expenses. The Company pays the administrative
                  expenses of the Plan, except loan set up and carrying fees and
                  redemption fees imposed on certain Fidelity funds.

         (5)      Payment of Benefits. Benefit payments are recorded when paid.

D.       RELATED PARTY TRANSACTIONS

         Certain Plan investments are shares of mutual funds managed by
         Fidelity. Fidelity is the trustee as defined by the Plan and,
         therefore, these transactions qualify as party-in-interest
         transactions. Fees paid by the Plan for the investment management
         services amounted to $8,472 and $6,997 for the years ended December 31,
         2001 and 2000, respectively. In addition, the Plan invests in shares of
         Quanex Corporation unitized common stock. Quanex Corporation is the
         Plan sponsor as defined by the Plan and, therefore, these transactions
         also qualify as party-in-interest transactions. As of December 31, 2001
         and 2000, the value of Quanex Corporation unitized common stock held by
         the Plan was $2,199,246 and $4,564,544, respectively.





E.       PLAN TERMINATION

         Although it has not expressed any intention to do so, the Company has
         the right under the Plan to terminate the Plan at any time subject to
         the provisions set forth in ERISA. In the event of Plan termination,
         the assets held by the Trustee under the Plan will be valued and fully
         vested, and each participant will be entitled to distributions
         respecting his or her account.

F.       FEDERAL INCOME TAX STATUS

         The Plan is subject to specific rules and regulations related to
         employee benefit plans under the Department of Labor and the Internal
         Revenue Service. The Plan has received a favorable letter of tax
         determination dated December 22, 1994. As such, the Plan is a qualified
         trust under Sections 401(a) and 401(k) of the Internal Revenue Code
         (the "Code") and, as a result, is exempt from federal income tax under
         Section 501(a) of the Code. The Company believes the Plan is currently
         designed and being operated in compliance with the applicable
         requirements of the Code. The Company believes the Plan was qualified
         and the related trust was tax-exempt as of the financial statement
         dates.
