INDEPENDENT AUDITORS' REPORT


The Benefits Committee
Quanex Corporation

Re:      Nichols Homeshield 401(k) Savings Plan

We have audited the accompanying statements of net assets available for benefits
of the Nichols Homeshield 401(k) Savings Plan (the "Plan") as of December 31,
1997 and 1996 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 generally accepted auditing
standards. 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,
1997 and 1996 and the changes in net assets available for benefits for the years
then ended in conformity with generally accepted accounting principles.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The accompanying supplemental schedules
of (1) investments as of December 31, 1997 and (2) 5% reportable transactions
for the year ended December 31, 1997 are presented for the purpose of additional
analysis and are not a required part of the basic financial statements but are
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. These schedules are the responsibility of the Plan's
management. Such schedules have been subjected to the auditing procedures
applied in our audit of the basic 1997 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.

A.       DESCRIPTION OF THE PLAN

         The following description of the Nichols-Homeshield 401(k) Savings Plan
         (the "Plan") is provided for general informational purposes only.
         Participants should refer to the Plan document for more complete
         information.

         (1)      General. The Plan was established on October 1, 1987, and was
                  amended and restated effective January 1, 1989, as a defined
                  contribution plan under Section 401(k) of the Internal Revenue
                  Code ("Code") which covers substantially all salaried and
                  non-union hourly employees at the Nichols-Homeshield division
                  of Quanex Corporation (the "Company") and bargaining unit
                  employees at the Lincolnshire, Illinois plant. The Plan is
                  subject to the provisions of the Employee Retirement Income
                  Security Act of 1974 ("ERISA"). 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.

         (2)      Contributions. Employees are eligible to make salary deferral
                  contributions to the Plan on the entry date next following the
                  date that the employee completes one month of service.
                  Participants may elect salary deferrals between 1% and 15% of
                  compensation as defined by the Plan agreement. 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)      Investment Options. Participants may direct allocation of 
                  their contributions to the following funds:

         (5)      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.

         (6)      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. As of December 31, 1997 and 1996, net assets
                  available for benefits included benefits of $3,479 and
                  $22,530, respectively, due to participants who had withdrawn
                  from participation in the Plan.

         (7)      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.
                  Loan set-up fees and carrying fees are paid by the participant
                  to Fidelity.

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)      Administrative Expenses. Administrative expenses of the Plan
                  are paid by the Company. Loan set up fees and carrying fees
                  are paid by the participant to Fidelity.

         (3)      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 fair value of the
                  common/commingled trust is at face value.

         (4)      Use of Estimates. The preparation of financial statements in
                  conformity with generally accepted accounting principles
                  requires the use of estimates and assumptions that affect the
                  reported amounts of assets and liabilities at the date of the
                  financial statements and the reported amounts of changes in
                  the net assets available for benefits during the reporting
                  period. The Plan's financial statements include amounts that
                  are based on management's best estimates and judgments. Actual
                  results could differ from these estimates.

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

C.       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.

D.       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 ("IRS"). The Plan is a qualified trust under Sections
         401(a) and 401(k) of the Code and, as a result, is exempt from taxation
         under Section 501(a) of the Code. The Plan received a favorable
         determination letter dated December 22, 1994 from the IRS. The Company
         believes that the Plan is currently designed and being operated in
         compliance with the applicable requirements of the Code. Therefore, it
         believes the Plan was qualified and the related trust was tax-exempt as
         of the financial statement dates.
