ITEM 1.   BUSINESS

General development of business

Lindberg is the largest commercial heat treating company in North America,
with operations in major industrial centers throughout the United States
and in Mexico.  The company serves more than 10,000 customers in diverse
industries, including commercial aerospace, automobile/light truck, heavy
truck/construction equipment, oil-field machinery, defense, consumer
products, tool and die, agricultural equipment and a variety of other
industries.  The company was founded in 1922 and, through both internal
growth and acquisitions, today operates in 15 states and in Mexico.

On February 17, 1999, the company acquired all of the outstanding shares of
Metal-Lab of Wisconsin, Inc. ("Metal-Lab"), located in Sturtevant, Wisconsin.
Metal-Lab primarily serves the tool and die industry.  Since November 1994,
the company has acquired nine companies in the United States, and continues to
seek other acquisitions.

In 1998, the company started its first heat treating operation in Mexico,
outside Monterrey.  The company intends the plant to be a base of operations
that could expand over time to meet other market needs, particularly in the
growing metal-working markets of northern Mexico.

On January 18, 1999, the company sold the assets of the remaining operation of
its discontinued Precision Products segment, Arrow-Acme Company, thereby
completing the divestiture of that segment.  As a result, the company
currently operates solely as a heat treating company, and reports only one
business segment.

Industry

Heat treating in the United States is performed in-house in captive heat
treating departments of manufacturers or externally by a commercial heat
treating company such as Lindberg.  Management believes that the commercial
heat treating industry captures about $2 billion in business annually, which
represents about 10-15% of the total amount of heat treating performed in the
U.S. -- the balance is performed in captive heat treating departments.
In-house heat treating facilities are typically part of a larger facility,
such as a steel mill or an automobile components factory, where large volumes
justify a captive operation.  Commercial heat treaters

                                    4
<PAGE> 5

are independent companies that specialize in heat treating or other metal
treatments and serve a large number of customers across a variety of
industries.

Due to the time and costs associated with transporting materials and
customers' need for quick turnaround times for heat treated products,
commercial heat treating has developed as a regional industry, with customers
typically located within 100 to 200 miles of the heat treating supplier.
Consequently, the commercial heat treating industry is highly fragmented.
Commercial heat treaters are concentrated in major industrial centers of
the country.  Management estimates that the top five commercial heat treating
companies in terms of revenues in the U.S. represent approximately 15-20% of
the commercial heat treating industry.

The fragmented nature of the commercial heat treating industry has presented
opportunity for consolidation.  Several factors have motivated smaller
commercial heat treating owners to sell to larger commercial heat treaters,
including increasingly burdensome regulatory and certification requirements,
capital expenditures necessary to remain competitive, increasing demand for
technical expertise, and succession planning considerations.  In addition, a
number of industry participants have acquired other heat treaters in order to
expand their geographical presence and provide expanded or enhanced service
capabilities.

Management expects outsourcing to be a continuing opportunity in the heat
treating industry.  Many smaller companies involved in the manufacture of
metal components outsource their heat treating requirements to commercial heat
treaters in order to avoid the significant cost of heat treating equipment.
In recent years, larger manufacturers have also outsourced heat treating
requirements due to the increased demand for technical expertise required in
heat treating and the relatively small portion of the total cost of the
finished product represented by heat treating.

Processes

Lindberg offers a wide range of heat treating processes for steel, aluminum,
cast iron, titanium alloys and other metals.  Processes are performed on
customer-provided products at various steps in the manufacturing cycle.  The
company does not maintain a raw material inventory or own work-in-process.
The range of processing offered by the company requires different types and
sizes of primary and secondary heat treating equipment.

Heat treating improves the mechanical properties, performance, durability and
wear resistance of metals and is an important step in many manufacturing
processes involving metals.  Heat treating can soften metal to improve
formability, make a part harder to improve strength, put a hard surface on a
relatively soft component to increase strength or abrasion resistance, put a
corrosion-resistant surface on an item that would otherwise corrode or temper
a brittle product.  Heat treated parts are essential to the operation of
automobiles, aircraft, spacecraft, consumer products, and heavy equipment of
every kind. Typical products that the company heat treats are aircraft
components, automotive parts, machine tools and dies, oil-field drill rig
parts, bearings, gears, axles, fasteners, camshafts, crankshafts and
cutting tools.

Heat treating is a process in which metal is heated and cooled under tight
controls.  Heat treating processes require three basic steps: (i) heating to a
specified temperature, (ii) holding at that temperature for the appropriate
amount of time, and (iii) cooling according to a prescribed method.
Temperatures may range as high as 2400oF, and time at temperature may vary
from a few seconds to as many as 60 hours or more.  Some materials are cooled
slowly in the furnace or in the air, but others must be cooled quickly, or
''quenched.'' Primary quenching media include water, oils, gases and polymer
solutions.  Each quenching medium has specific characteristics that make it
well-suited for certain applications.

                                    5
<PAGE> 6

Of the company's wide range of heat treating processes, the following are the
most common:

Hardening, Tempering and Annealing are performed using a variety of equipment,
including electric and gas furnaces, neutral salt baths, press quenching and
vacuum furnaces.  The purpose of these processes is to create the ideal
metallurgical properties in the treated material.

Solution Treating and Aging is performed on aluminum, titanium and stainless
steel pieces to create desired properties of ductility and hardness throughout
the piece.

Surface Treating utilizes a specialized furnace to heat steels to an
appropriate temperature.  Once the selected temperature is achieved, a carbon
or nitrogen rich gas is introduced to the furnace and elements within the gas
diffuse into the surface of the steel.  The surface of the material is
transformed into a tougher, more wear resistant structure, while the core of
the material retains its ductility.  Types of surface treatment include
carburizing, nitriding, carbo nitriding and ferritic nitrocarburizing.

Brazing is a process which uses heat treating to bond two different pieces.
The company utilizes electric furnaces, vacuum furnaces and induction in its
brazing process.

Lindberg has established itself as a leading commercial heat treater based on
its level of quality and service, technical expertise and network of
facilities, industry certifications and national reputation.  The company
delivers its services on a timely basis, while its technical expertise
provides the capability to develop customized solutions that meet specific
customer needs.  The company's plants are recognized with third-party quality
endorsements, such as ISO 9000, QS 9000, NADCAP, and AS 9000 and have approved
vendor status from many customers.  These certifications and approvals enable
the company to heat treat products manufactured for some of the largest
domestic manufacturers.

Operations

Because the industry is fragmented and localized, the company's operations are
decentralized so each plant can react quickly and effectively to local market
conditions.  The company's divisions have considerable autonomy in most
operational areas, including sales, pricing, hiring and participation in
strategic planning for their respective local markets.  In addition, the
company's facilities tend to be clustered in certain geographic areas, which
permits individual facilities to utilize additional capacity or other heat
treating processes at alternate sites if necessary.

Each plant is equipped with furnaces of various types and sizes, and support
equipment.  Many pieces of primary equipment are capable of running several
different processes.  Auxiliary items include fixtures, atmosphere generators,
material handling equipment, cleaning equipment and metallurgical testing
equipment.  Key suppliers provide electricity and natural gas.  Other
important purchased materials include quench oils, process gases, fixtures,
maintenance supplies, laboratory and testing supplies and auxiliary equipment.
The company has not experienced any material restrictions by its suppliers of
sources of energy or any other significant raw materials necessary in the
process of heat treating.

The company services certain customers which are seasonal in nature.  However,
in large part because of compensating variations and the large majority of
non-seasonal customers, the company does not view its business as seasonal.

                                    6
<PAGE> 7

Customers

The company serves over 10,000 customers that range from owner-operated job
shops to large, national manufacturing companies.  At the plant level, each of
the company's heat treating facilities serve an average of 400 customers. The
company's largest direct customer accounted for less than 3% of the company's
net sales in 1999.  The ten largest customers accounted for approximately 13%
of net sales in 1999.

The company's customers are primary suppliers to companies operating in a
variety of manufacturing industries, including commercial aerospace,
automobile/light truck, heavy truck/construction equipment, oil-field
machinery, defense, consumer products, building components, tool and die,
agricultural equipment and a variety of other industries.  The company also
provides heat treating services directly to end users in such industries.

Management estimates that customers serving the commercial aerospace industry
currently account for approximately 24% of the company's net sales and that
customers serving the automobile/light truck industry account for
approximately 15% of net sales.  Because the company provides heat treating
services at different stages of the manufacturing process to a wide range of
manufacturers and their suppliers in a variety of industries, the company
cannot measure precisely its penetration of specific industries.

Most of the company's plants are located in major industrial areas of the
Midwest, California, Texas or the Northeast, usually serving customers in that
region.  Because customers generally want to minimize the expense and risks
associated with transporting their products over long distances to and from
commercial heat treating plants, they tend to prefer heat treaters located in
close proximity to their own facilities.  Customers often deliver and pick up
their parts, or the plant provides some delivery with its own trucking.  This
market configuration has led to some degree of specialization for most of the
company's plants, with each plant focusing on the particular needs of the
customers in its area.  The company operates with a limited backlog due to the
localized nature of its businesses and the customers' necessity for a quick
turnaround.  The company's plants typically process orders within one to five
days; therefore, backlog in facilities is generally estimated to be less than
one week.

The company also offers dedicated heat treating services to certain larger
customers under long-term contracts through its Strategic Partnership 2000
("SP 2000") program. This program was developed to (i) provide services to
manufacturers that perform their own heat treating in-house, (ii) retain
existing customers whose high heat treating volume may justify moving the
process in-house and (iii) capture additional volume from customers that may
be using multiple heat treaters.

Competition

Due to the regional and highly fragmented nature of the commercial heat
treating industry, each plant has competition of varying degrees of intensity.
Competition consists of local heat treating owner-operators and certain
facilities of larger heat treating companies.  Each plant competes in its
market on the basis of service and on-time delivery, quality and price.  Local
management at each of the company's facilities is largely responsible for its
own pricing and cost control, and thus has the flexibility to respond to local
market conditions.

National competition in the commercial heat treating industry is limited.
There are competitors in particular localities that are larger than the
company's facility located in those markets.  Such competitors may also be
divisions of larger companies and, therefore, have access

                                    7
<PAGE> 8

to additonal resources.  Competition also exists from in-house heat treating
facilities of manufacturers, although the company also considers such
manufacturers as potential customers.

Management believes that the company's national presence, size and reputation
for quality and service position it to supply many of the nation's largest
corporations.

Associates

Currently, the company employs approximately 1,050 associates, as compared to
1,220 associates at December 31, 1998.  Of these associates, 132 are covered
by collective bargaining agreements.  One agreement is currently under renewal
negotiations and four are subject to such in 2001.  The company believes that
its employee relations are good.

Environmental Regulation

The company employs some environmentally hazardous materials.  The company has
made expenditures to comply with laws and regulations relating to the
protection of the environment, including studies, investigations and
remediation of ground contamination, and expects to make such expenditures in
the future in its efforts to comply with existing and future requirements.
While such expenditures to date have not materially affected the company's
capital expenditures, competitive position, financial condition or results of
operations, there can be no assurance that more stringent regulation or
enforcement in the future will not have such effects.

The company has notified state authorities of a possible need for remediation
at three sites it currently operates.  At all such sites, costs which may be
incurred are difficult to accurately predict until the level of contamination
is determined, and would be subject to increase if more contamination is
discovered during investigation or remediation or if state authorities require
more remediation than anticipated.  Such costs may be less if the
contamination proves to be less than currently expected and to the extent
costs are covered by insurance or are allocable to others.

The company has also been notified by various state and federal governmental
authorities that they believe the company may be a ''potentially responsible
party'' or otherwise have responsibility with respect to clean-up obligations
at one waste disposal site which was never owned or operated by the company.
The company is participating in a settlement with the relevant authorities or
other parties believed by the company to be responsible for clean-up
obligations and further believes its responsibility to be of a minor nature.
Management believes that the ultimate outcome will not have a material effect
on the company's financial condition or results of operations.

At December 31, 1999, the company had reserves of $1.7 million to cover future
environmental related costs.  Such reserves give no effect to possible
recoveries from insurers or other potentially responsible parties nor do they
reflect any discount for the several years over which investigation or
remediation amounts may be paid out.

Patents, Trademarks and Licenses

The company is a minority (17%) stockholder in a consortium of industrial
partners called Thixomat, Inc.  Thixomat, Inc. was formed in 1989 to promote
and commercialize the ThixomoldingTM technology, a specialized molding
process.

The company's facilities are suitable for their respective uses and are, in
general, adequate for the company's current needs.  Those providing products
in markets where economic activity is strong at any particular time operate at
relatively high levels of plant utilization.  The company believes that it has
sufficient capacity at its current facilities to absorb additional workloads
at reasonably anticipated levels.

ITEM 3.  LEGAL PROCEEDINGS

The company was the subject of an investigation by the government and a qui-
tam (whistle-blower) lawsuit regarding alleged violations of the Federal False
Claims Act and wrongful termination.  The company learned of the lawsuit in
May 1998.  The activities that were the subject of the investigation and
lawsuit related to only one plant, and in the fourth quarter 1998, the company
established reserves for the potential settlement of this claim.  In the first
quarter of 1999, the company reached a settlement in principle with the
government and the plaintiff on terms consistent with the reserves previously
established.  The company completed the settlement in the second quarter of
1999.

The company is a party to various other lawsuits and claims arising in the
ordinary course of business.  See also page 8, section entitled "Environmental
Regulation."  After review and consultation with legal counsel, the company
believes that any liability resulting from these matters would not materially
affect its financial condition or results of operations.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

There were no matters submitted to a vote of security holders during the
fourth quarter of 1999.

To the Stockholders of
Lindberg Corporation:

We have audited, in accordance with generally accepted auditing standards, the
consolidated financial statements included in Lindberg Corporation's annual
report to stockholders incorporated by reference in this Form 10-K and have
issued our report thereon dated January 21, 2000.  Our audit was made for the
purpose of forming an opinion on those statements taken as a whole.  The
schedule listed in the index is the responsibility of the company's management
and is presented for purposes of complying with the Securities and Exchange
Commission's rules and is not part of the basic financial statements.  This
schedule has been subjected to the auditing procedures applied in the audit of
the basic financial statements and, in our opinion, fairly states in all
material respects the financial data required to be set forth therein in
relation to the basic financial statements taken as a whole.
