                          INDEPENDENT AUDITORS' REPORT





The Benefits Committee
Quanex Corporation
Houston, Texas

Re:  Quanex Corporation Hourly Bargaining Unit Employees Savings Plan

We have audited the accompanying statements of net assets available for benefits
of the Quanex Corporation Hourly Bargaining Unit Employees Savings Plan (the
"Plan") as of December 31, 1998 and 1997 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,
1998 and 1997 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, 1998 and (2) 5% reportable transactions
for the year ended December 31, 1998 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. The supplemental information by fund in the statements on
net assets available for benefits is presented for the purpose of additional
analysis rather than to present the net assets available for benefits of the
individual funds. The supplemental schedules and the supplemental information by
fund is the responsibility of the Plan's management. Such supplemental schedules
and supplemental information by fund have been subjected to the auditing
procedures applied in our audit 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.

                               QUANEX CORPORATION
                  HOURLY BARGAINING UNIT EMPLOYEES SAVINGS PLAN

                          NOTES TO FINANCIAL STATEMENTS
                     YEARS ENDED DECEMBER 31, 1998 AND 1997



A.   DESCRIPTION OF THE PLAN

     The following description of the Quanex Corporation Hourly Bargaining Unit
     Employees 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, originally named the Quanex Corporation Hourly
          Employees Savings Plan, became effective January 1, 1989 and is
          sponsored by Quanex Corporation (the "Company"). The Plan began
          receiving contributions in April 1989. The Plan is a defined
          contribution plan which is subject to the Employee Retirement Income
          Security Act of 1974 ("ERISA"). The Plan is a voluntary savings plan
          in which hourly employees of certain divisions of the Company are
          eligible to participate after completing three months of active
          service. 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. Participants may elect to contribute up to 15% of their
          before-tax or after-tax compensation as defined by the Plan agreement.
          The Plan was amended effective July 1, 1994 to include LaSalle Steel
          Company hourly employees (Note E). All plan provisions applied to the
          LaSalle Steel Company hourly employees with the addition of an
          employer matching contribution that did not exceed 5% of the member's
          considered compensation.

     (3)  Participant Accounts. Each participant's account is credited with the
          participant's contribution and an allocation of investment income,
          which is 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:

          Fidelity Puritan Fund - invests in domestic and foreign common stocks,
          preferred stocks and bonds.

          Fidelity Magellan Fund - invests in equity and debt securities of
          foreign and domestic companies.

          Fidelity Contrafund - invests in equities of foreign and domestic
          companies.

          Fidelity Growth and Income Fund - invests in equity and debt
          securities of foreign and domestic companies.

          Fidelity Retirement Growth Fund - invests in common stocks and other
          securities.

          Fidelity Overseas Fund - invests in foreign equity and debt
          securities.

          Fidelity Balanced Fund - invests in common and preferred stocks and
          bonds.

          Fidelity Blue Chip Fund - invests in domestic and foreign common
          stocks.

          Fidelity Low-Priced Stock Fund - invests in domestic and foreign
          stocks.



   6

          Fidelity Government Money Market Fund - composed of short-term U.S.
          government obligations.

          Templeton Foreign Fund - invests in foreign securities.

          Neuberger & Berman Partner Trust Fund - invests in common stocks.

          Quanex Corporation Common Stock - invests exclusively in the common
          stock of Quanex Corporation.

          Common/Commingled Trust - invests in investment contracts issued by
          insurance companies, banks and other financial institutions.

     (5)  Vesting. Participants are immediately vested in their contributions
          and the related earnings. Vesting in the employer's matching
          contributions for Lasalle Steel Company employees is 0% for less than
          one year of service graduating to 100% for five or more years. Upon
          death, retirement or total and permanent disability, the participant
          or beneficiary becomes immediately vested in the employer's
          contribution. In the event of termination, nonvested portions of
          employer's contributions are immediately forfeited by participants and
          utilized to reduce future employer matching contributions.

     (6)  Payment of Benefits. Upon termination of service, the participant may
          elect to receive a lump sum distribution equal to the total amount of
          vested benefits in his or her account. As of December 31, 1998 and
          1997, net assets available for benefits included benefits of $34,543
          and $7,794, respectively, due to participants who had withdrawn from
          participation in the Plan.

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 using the last recorded sales
          price. The fair value of the common/commingled trust is at face value.

     (3)  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.

     (4)  Administrative Expenses. The Company pays all administrative expenses.

     (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 (the "IRS"). The Plan has received a favorable letter of tax
     determination dated April 25, 1997. 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.

E.   TRANSFER OF ASSETS

     Effective April 18, 1997, Quanex Corporation sold its LaSalle Steel Company
     subsidiary ("LaSalle") to Niagara Corporation. On December 1, 1997, assets
     of the Plan in the amount of $2,135,383 were transferred to the trustee of
     the LaSalle Steel Company Hourly Bargaining Unit Employees Savings Plan.

     On December 3, 1997, Michigan Seamless Tube Company, the Gulf States Tube
     and the Tube Group Office divisions of Quanex Corporation (the "Tube
     Group") were sold to Vision Metals, Inc. In plan year 1998, assets of the
     Plan attributable to the Tube Group employees in the amount of $4,700,123
     were transferred to the new qualified savings plan established by Vision
     Metals, Inc.

F.   RELATED PARTY TRANSACTIONS
