Shareholders for the year ended December 31, 1998.

PART I

ITEM 1 - BUSINESS

(a) GENERAL DEVELOPMENT OF BUSINESS

Ampco-Pittsburgh Corporation (the "Corporation") was incorporated in
Pennsylvania in 1929. In 1998, the Corporation reclassified the way it reports
its businesses into three segments:

Forged Steel Rolls Segment
- --------------------------

Union Electric Steel Corporation produces forged hardened steel rolls and
is headquartered in Carnegie, Pennsylvania.

Air and Liquid Processing Segment
- ---------------------------------

Aerofin Corporation produces finned tube heat exchange coils and is
headquartered in Lynchburg, Virginia. Buffalo Air Handling Company is
headquartered in Amherst, Virginia and manufactures large standard and custom
air handling systems. Buffalo Pumps, Inc. manufactures centrifugal pumps and is
headquartered in North Tonawanda, New York.

Plastics Processing Machinery Segment
- -------------------------------------

New Castle Industries, Inc. and its subsidiaries primarily produce feed
screws, barrels and chill rolls and are headquartered in New Castle,
Pennsylvania. F. R. Gross Company, located in Stow, Ohio, manufactures heat
transfer rolls.

(b) FINANCIAL INFORMATION ABOUT INDUSTRY SEGMENTS

The sales and operating profit of the Corporation's three segments and the
identifiable assets attributable to each segment for the three years ended
December 31, 1998 are set forth in Note 14 (Business Segments) on pps. 17 and 18
of the Annual Report

to Shareholders for the year ended December 31, 1998 which is incorporated
herein by reference.

The Forged Steel Rolls segment manufactures forged hardened steel rolls for
producers of steel, aluminum and other metals. The operations comprising the
Air and Liquid Processing segment produce heat exchange coils, air handling
systems and pumps for the construction, power generation, refrigeration,
chemical processing and marine defense industries and a variety of other
industrial and commercial customers. The Plastics Processing Machinery segment
produces components including feed screws, barrels, heat transfer rolls and
chill rolls for use by original equipment machinery manufacturers and processors
principally serving the plastics industry. In all three segments, the products
are dependent on engineering, principally custom designed and are sold to
sophisticated commercial and industrial users in the United States and foreign
countries.

No one customer's purchases in any segment were material to the
Corporation. Contracts that may be subject to renegotiation or termination are
not material to the Corporation. The Corporation's businesses are not seasonal
but are subject to the cyclical nature of the industries and markets served.

For additional information on the products produced and financial
information about each segment, see pp. 3 through 7 and Note 14 on pps. 17 and
18 of the Annual Report to Shareholder for the year ended December 31, 1998
which are incorporated herein by reference.

Raw Materials
- -------------

Raw materials used in all segments are generally available from many
sources and the Corporation is not dependent upon any single supplier for any
raw material. Certain of

the raw materials used by the Corporation have historically been subject to
variations in price. The Corporation generally does not purchase or arrange for
the purchase of a major portion of raw materials significantly in advance of the
time it requires them.

Patents
- -------

While the Corporation holds some patents, trademarks and licenses, in the
opinion of management they are not material to any segment of the Corporation's
business other than in protecting the goodwill associated with the names under
which products are sold.

Working Capital
- ---------------

Each segment of the Corporation's business maintains levels of inventory,
which generally reflect normal requirements and are believed to reflect the
practices of its industries. Production in all segments is generally to custom
order and requires inventory levels of raw materials or semi-finished products
with only a limited level of finished products. The Corporation extends credit
terms consistent with practices of the industries served.

Backlog
- -------

The backlog of orders at December 31, 1998 was approximately $100,000,000
compared to a backlog of $115,200,000 at year end 1997. Most of those orders
are expected to be filled in 1999.

Competition
- -----------

The Corporation faces considerable competition from a large number of
companies in each segment. The Corporation believes, however, that it is a
significant factor in each of the principal markets which it serves.
Competition in all segments is based on quality, service, price and delivery.

Forged Steel Rolls Segment
--------------------------

Union Electric Steel Corporation is considered the largest producer of
forged hardened steel rolls in the United States, which are sold to steel and
aluminum companies throughout the world. In addition to several domestic
competitors, several major European and Japanese manufacturers also compete in
both the domestic and foreign markets.

Air and Liquid Processing Segment
---------------------------------

Buffalo Pumps, Inc. produces a line of centrifugal pumps serving
refrigeration, power generation and marine defense industries and competes with
many other producers. Aerofin Corporation produces heat exchange coils used by
the commercial and industrial construction, process and utility industries.
Buffalo Air Handling Company produces standard and custom air handling systems
used in commercial and industrial buildings. Aerofin and Buffalo Air Handling
have several major competitors in each of their markets.

Plastics Processing Machinery Segment
-------------------------------------

New Castle Industries and its subsidiaries primarily produce feed screws,
barrels, and chill rolls for use principally in the plastics processing industry
and compete with a number of small regional companies. F. R. Gross Co.
produces heat transfer rolls for the plastics, paper, packaging, printing and
converting industries and also competes with a number of small regional
companies.

Research and Development
- ------------------------

As part of an overall strategy to develop new markets and maintain
leadership in each of the industry niches served, each of the Corporation's
businesses in all three segments incur expenditures for research and
development. The activities that are undertaken are designed to develop new
products, improve existing products and

processes, enhance product quality, adapt products to specific customer
requirements and reduce costs. In the aggregate, these expenditures generally
do not exceed $1,000,000 per year.

Environmental Protection Compliance Costs
- -----------------------------------------

Expenditures for environmental control matters were not material to any
segment in 1998 and such expenditures are not expected to be material in 1999.

Employees
- ---------

In December, 1998, the Corporation had 1,332 active employees, of whom 437
were sales, executive, administrative, engineering and clerical personnel.
Approximately 66% of the production and craft hourly employees are members of
various unions.

Year 2000
- ---------

See Management's Discussion and Analysis of Financial Condition and Results
of Operations on pps. 19 through 23 of the Annual Report to Shareholders for the
year ended December 31, 1998 which is incorporated herein by reference.

(d) FINANCIAL INFORMATION ABOUT FOREIGN AND DOMESTIC OPERATIONS AND EXPORT
SALES

The Corporation's only foreign operation is a plant located in Belgium
(Union Electric Steel N.V.) that manufactures forged hardened steel rolls
principally for the European markets. For financial information relating to
foreign and domestic operations see Note 14 (Business Segments) on pps. 17 and
18 of the accompanying Annual Report which is incorporated herein by reference.

* Facility is leased.

(1) The Corporation holds real estate for sale in Plymouth, MI.

(2) The Corporate office space is leased as are several small domestic sales
offices. All of the owned facilities are adequate and suitable for their
respective purposes. There were no facilities idled during 1998.

(3) The Corporation estimates that all of its facilities were operated within
75% to 95% of their normal capacity during 1998. Normal capacity is defined
as capacity under approximately normal conditions with allowances made for
unavoidable interruptions, such as lost time for repairs, maintenance,
breakdowns, set-up, failure, supply delays, labor shortages and absences,
Sundays, holidays, vacation, inventory taking, etc. The number of work
shifts are also taken into consideration.

ITEM 3 - LEGAL PROCEEDINGS

The Corporation has been involved in various claims and lawsuits incidental
to its business. In the opinion of management, the Corporation has meritorious
defenses in those cases and believes that, in the aggregate, any liability will
not have a material effect on the financial position of the Corporation.

A lawsuit was commenced in May, 1991 against the Corporation and its
subsidiary, Vulcan, Inc. ("Vulcan"), arising out of the filing of a petition
under Chapter 11 of the United States Bankruptcy Code in October, 1990 by
Valley-Vulcan Mold Company (the "Partnership"), a 50/50 partnership formed in
September, 1987 between Vulcan and Valley Mould Corporation, a subsidiary of
Microdot, Inc. Microdot and Valley are unrelated to the Corporation and were
also defendants in the lawsuit. The Partnership acquired the ingot mold
businesses of each of the partners. On June 10, 1993, Microdot also filed a
Petition under Chapter 11 of the United States Bankruptcy Code. In October,
1994, Microdot's Chapter 11 case was converted to a Chapter 7 liquidation.

In the lawsuit, Official Unsecured Creditors' Committee of Valley-Vulcan
--------------------------------------------------------
Mold Company v. Microdot, Inc., Valley Mould Corporation, Ampco-Pittsburgh
- --------------------------------------------------------------------------
Corporation and Vulcan, Inc., the plaintiff, allegedly on behalf of the debtor
- ----------------------------
Partnership, filed a proceeding in the United States Bankruptcy Court for the
Northern District of Ohio against Microdot, Valley, Vulcan and the Corporation,
seeking to set aside the Corporation's liens on the Partnership's assets, to
hold all defendants liable for the debts of the Partnership, and return of all
money received by any of the defendants from the Partnership and out of the
proceeds of a loan to the Partnership by a third-party lender, alleged to be at
least $9.35 million. The Corporation's liens secure a guaranty that it was
required to give with respect

to a Vulcan obligation that was assumed by the Partnership, and a $500,000 loan
made to the Partnership.

The trial of this lawsuit was held the week of October 4, 1993. In April,
1994 the Court issued a judgment in favor of the Corporation. Under the Court's
decision, all claims against the Corporation were denied. All claims against
Vulcan were also denied except for its liability as a general partner. Vulcan's
only asset is its interest in the partnership, which has no value, and
accordingly the judgment will not have any adverse effect on the Corporation.
In May, 1994, plaintiff appealed to the United States District Court, Northern
District of Ohio, Eastern Division. In 1998, upon stipulation of the parties,
the Court ordered this appeal transferred to the Bankruptcy Appellate Panel for
the Sixth Circuit ("BAP"). The BAP has not yet rendered its decision.

The Corporation is involved in various environmental proceedings which all
involve discontinued operations. In some of those proceedings, the Corporation
has been designated as a Potentially Responsible Party ("PRP"). However, the
Corporation believes that in most instances it is either a de minimis
----------
participant based on information known to date and the estimated quantities of
waste at these sites and/or that it is entitled to indemnity from the successors
of the operations alleged to be involved. Based on the current estimate of
cleanup costs and proposed allocation of that cost among the various PRP groups,
for all environmental matters considered in the aggregate, the liability to the
Corporation would not be material.

ITEM 4 - SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
No matter was submitted to a vote of security holders during the fourth
quarter.

PART II

ITEM 5 - MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED
STOCKHOLDER MATTERS

Description of Common Stock - The Company is authorized to issue 20,000,000
shares of Common Stock, par value $1.00 per share, and 3,000,000 shares of
Preference Stock, without par value. None of the Preference Stock has been
issued but the Board of Directors of the Company may, without further approval
of shareholders of the Company, issue the Preference Stock in one or more series
with such rights, voting powers, preferences, qualifications, limitations,
restrictions, and special or related rights as the Board of Directors may
determine. Subject to the foregoing, holders of Common Stock are entitled to
receive such dividends (in cash, stock or otherwise) as may be determined by the
Board of Directors and may be legally available for that purpose and, in the
event of liquidation, to share ratably in assets available for distribution.
Subject to the voting rights, if any, of holders of Preference Stock hereafter
issued by the Company, each holder of Common Stock is entitled to one vote for
each share held of record on all matters voted on by shareholders and there are
cumulative voting rights in electing directors. At the Annual Meeting of
Shareholders, held on April 26, 1984, the Shareholders approved amendments to
the Company's Articles of Incorporation that (1) included in the Articles the
provision already in the Company's By-laws creating a classified board of three
classes, (2) permit directors to be removed by shareholder vote without cause,
but only if shareholders entitled to cast at least 75% of the votes which all
shareholders would be entitled to cast in

an annual election of directors shall vote for such removal (subject to
provisions to protect cumulative voting rights) and (3) increased the
shareholder vote required, from a majority vote to 75% of the votes which all
shareholders would be entitled to cast in an annual election of directors, to
amend or repeal or to adopt any provision inconsistent with the Articles or the
By-laws (whether adopted by the Board of Directors or the shareholders), unless
such amendment has been approved by at least a two-thirds vote of the whole
Board of Directors.

The holders of Common Stock have no subscription, redemption, conversion
or preemptive rights. All outstanding shares of Common Stock are fully paid and
nonassessable.

The Common Stock is listed on the New York and Philadelphia Stock
Exchanges. The Transfer Agent and Registrar for the Common Stock is ChaseMellon
Shareholder Services.

The Company furnishes its shareholders quarterly unaudited reports for the
first three fiscal quarters and annual reports containing audited financial
statements for each fiscal year.

LLP ("D&T") as the independent accountants for the year 1999.

disclaimer of opinion and were not qualified or modified as to uncertainty,
audit scope or accounting principles; (b) there were no disagreements with PwC
on any matters of accounting principles or practices, financial statement
disclosure or auditing scope or procedure, which

disagreements, if not resolved to the satisfaction of PwC would have caused PwC

to the Executive Officers and other employees, to which the Corporation makes
annual contributions, as required, in amounts determined by the Plan's
actuaries. The Plan does not have an offset for Social Security and is fully
paid for by the Corporation. Under the Plan, employees become fully vested
after five years of participation and normal retirement age under the Plan is
age 65 but actuarially reduced benefits may be available for early retirement at
age 55. The benefit formula is 1.1% of the highest consecutive five year
average earnings in the final ten years, times years of service. Federal law
requires that 5% owners start receiving a pension no later than April 1
following the calendar year in which the age 70-1/2 is reached. Louis Berkman
is currently receiving $5,147 a month pursuant to the Plan. As an active
employee, Mr. Berkman continues to receive credit for additional service
rendered after age 70-1/2.

The Corporation adopted a Supplemental Executive Retirement Plan (SERP) in
1988 (amended and restated in 1996) for all officers listed in the compensation
table, except Louis Berkman, and certain key employees, covering retirement
after completion of ten years of service and attainment of age 55. The combined
retirement benefit at age 65 provided by the Plan and the SERP is 50% of the
highest consecutive five year average earnings in the final ten years of
service. The participants are eligible for reduced benefits for early
retirement at age 55. A benefit equal to 50% of the benefit otherwise payable
at age 65 is paid to the surviving spouse of any participant, who has had at
least five years of service, commencing on the later of the month following the
participant's death or the month the participant would have reached age 55. In
addition, there is an offset for

pensions from other companies. Certain provisions, applicable if there is a
change of control, are discussed below under Termination of Employment and
Change of Control Arrangement.

The following shows the estimated annual pension that would be payable,
without offset, under the Plan and the SERP to the individuals named in the
compensation table assuming continued employment to retirement at age 65, but no
change in the level of compensation shown in such table:

Louis Berkman (1)
Robert A. Paul $198,250
Ernest G. Siddons $176,500 (2)
Robert F. Schultz $ 76,375

- ----------------

(1) Mr. Berkman is currently receiving a pension pursuant to the Plan as
described above.
(2) Assumes employment until end of year.

In 1998, each Director who was not employed by the Corporation received an
annual retainer of $6,000 (payable quarterly), $1,000 for each Board meeting
attended and $500 for each Committee meeting attended. Attendance can be either
in person or by telephonic connection. Directors do not receive a fee for
either Board or Committee meetings if they do not attend.

(d) TERMINATION OF EMPLOYMENT AND CHANGE OF CONTROL ARRANGEMENTS

The Chairman, President, and Executive Vice President have two year
contracts (which automatically renew for one year periods unless the Corporation
chooses not to extend) providing for compensation equal to five times their
annual compensation (with a provision to gross up to cover the cost of any
federal excise tax on the benefits) in the

event their employment is terminated (including a voluntary departure for good
cause) and the right to equivalent office space and secretarial help for a
period of one year after a change in control. The remaining officer named in the
compensation table and a certain key employee have two year contracts providing
for three times their annual compensation in the event their employment is
terminated after a change in control (including a voluntary departure for good
cause). In addition, each of the Vice President Finance, Group Vice President
and Corporate Secretary have two year contracts providing for two times their
annual compensation in the event their employment is terminated after a change
in control (including a voluntary departure for good cause). All of the
contracts provide for the continuation of employee benefits, for three years for
the three senior executives and two years for the others, and the right to
purchase the leased car used by the covered individual at the Corporation's then
book value. The same provisions concerning change in control that apply to the
contracts apply to the SERP and vest the right to that pension arrangement. A
change of control triggers the right to a lump sum payment equal to the present
value of the vested benefit under the SERP if applicable.

(e) SALARY COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION IN COMPENSATION
DECISIONS

A Salary Committee is appointed each year by the Board of Directors.
Committee members abstain from voting on matters which involve their own
compensation arrangements. The Salary Committee for the year 1998 was comprised
of four Directors: William D. Eberle, who is Chairman of the Committee, Louis
Berkman, Leonard M. Carroll and Carl H. Pforzheimer, III.

Louis Berkman is Chairman of the Board of Directors and the Executive
Committee. He is also the President and a Director of The Louis Berkman Company.
The Corporation's

President and Chief Executive Officer is also an officer and director of The
Louis Berkman Company.

The Louis Berkman Company had certain transactions with the Corporation
which are more fully described under Item 13 "Certain Relationships and Related
Transactions."

(f) SALARY COMMITTEE REPORT ON EXECUTIVE COMPENSATION

The Salary Committee approves salaries for executive officers within a
range from $150,000 up to $200,000 and increases in the salary of any executive
officer, which would result in such officer earning a salary within such range.
Salaries of $200,000 per year and above must be approved by the Board of
Directors after a recommendation by the Salary Committee. Salaries for
executive officers below the level of $150,000 are set by the Chairman,
President and Executive Vice President of the Corporation.

The compensation of the Chief Executive Officer of the Corporation, as well
as the other applicable executive officers, is based on an analysis conducted by
the Salary Committee. The Committee does not specifically link remuneration
solely to quantitative measures of performance because of the cyclical nature of
the industries and markets served by the Corporation. In setting compensation,
the Committee also considers various qualitative factors, including competitive
compensation arrangements of other companies within relevant industries,
individual contributions, leadership ability and an executive officer's overall
performance. In this way, it is believed that the Corporation will attract and
retain quality management, thereby benefitting the long-term interest of
shareholders.

In 1998, the Salary Committee reviewed and approved salary increases and
had previously approved an incentive program for 1998 covering Louis Berkman,
Robert A. Paul and Ernest G. Siddons ("participants"). Incentive payments were
to be determined, based exclusively on the Corporation's 1998 income from
operations performance as

compared to the Corporation's business plan. These payments were to be limited
to 30% of base salary of participants. In 1998, the participants earned
incentives of $66,000, $66,000 and $59,000 respectively.

This report of the Salary Committee shall not be deemed incorporated by
reference by any general statement incorporating by reference this 10-K report
into any filing under the Securities Act of 1933 or under the Securities
Exchange Act of 1934, except to the extent that the Corporation specifically
incorporates this report and the information contained herein by reference, and
shall not otherwise be deemed filed under such Acts.
