Mesothelioma Lawyer Ohio: Legal Guide for Cleveland-Cliffs Middletown Works Asbestos Exposure

A Resource for Former Employees, Their Families, and Anyone Diagnosed with Mesothelioma or Asbestosis

What You Need to Know Right Now

You just got a diagnosis. Or someone you love did. Before anything else, understand this: the clock is already running on your legal rights.

For decades, the Middletown, Ohio steel mill — now operated by Cleveland-Cliffs Inc. — may have exposed thousands of workers to asbestos-containing materials. Steelmaking requires extreme heat and pressure. Asbestos was the industrial solution for insulation, sealing, and fireproofing throughout most of the twentieth century. Workers in maintenance, millwright, pipefitter, and construction trades may have been exposed to asbestos-containing products from Johns-Manville, Garlock Sealing Technologies, Owens-Corning/Owens-Illinois, Eagle-Picher Industries, Armstrong World Industries, W.R. Grace, Celotex Corporation, and Crane Co.

Those workers — now in their 60s, 70s, and 80s — are developing mesothelioma, asbestosis, and lung cancer at high rates. If you worked at the Cleveland-Cliffs Middletown Works and have been diagnosed with an asbestos-related disease, contact an asbestos attorney immediately. You may be entitled to substantial compensation.

Urgent Legal Notice: Ohio has a 2-year statute of limitations for asbestos personal injury claims under Ohio Rev. Code § 2305.10. That clock starts at diagnosis — not at the time of exposure. Missing this deadline ends your right to compensation permanently. Pending legislation for 2026, specifically

Part I: The Facility and Its History

An Integrated Steel Mill with Decades of Asbestos Use

The Middletown, Ohio facility traces its roots to the late nineteenth century, when proximity to coal fields, iron ore shipping routes, and the Great Lakes made the region a natural location for steelmaking. The plant grew into one of the most productive flat-rolled steel sites in the United States.

Corporate ownership timeline:

  • Armco Steel Corporation operated the facility as a flagship production plant for most of the twentieth century
  • AK Steel emerged from the Armco and Kawasaki Steel merger in the 1990s and continued Middletown operations
  • Cleveland-Cliffs Inc. acquired AK Steel in 2020

Facility naming note: The facility is properly identified as the Cleveland-Cliffs Middletown Works — formerly AK Steel Middletown Works, formerly Armco Steel Middletown. Workers and attorneys will encounter all three names when researching exposure history. All three matter when pulling employment records, OSHA inspection files, and trust fund claim documentation.

Scale of Operations and Exposure Points

At its peak, the Middletown Works ran every stage of steelmaking from raw materials to finished product. That scale created multiple points where workers may have contacted asbestos-containing materials:

  • Coke ovens — converting coal into coke fuel
  • Blast furnaces — smelting iron ore into pig iron
  • Basic oxygen furnaces (BOFs) and steelmaking vessels
  • Continuous casting operations
  • Hot strip mills and cold rolling mills
  • Annealing furnaces and finishing lines
  • Power generation and steam distribution systems
  • Pipe, valve, and mechanical infrastructure throughout the plant

Every one of these operations ran at extreme heat. For most of the twentieth century, managing that heat meant asbestos-containing materials were present throughout the facility.

Part II: Why Asbestos Was Used Throughout Steel Mills

Properties That Drove Industrial Adoption

Asbestos possessed properties that manufacturers and facility operators found difficult to replace:

  • Withstands temperatures above 1,000°F without igniting or degrading
  • High tensile strength under mechanical stress
  • Resistant to most acids and alkalis
  • Effective thermal and electrical insulation
  • Bonds readily with cement, resin, and other materials
  • Abundant and inexpensive through most of the twentieth century

In a steel mill where molten metal flows above 2,800°F, steam systems run under high pressure, and coke ovens require continuous high-heat insulation, asbestos-containing materials were specified for the most demanding thermal management jobs in the facility.

The Asbestos Exposure Timeline

Asbestos-containing material use in American integrated steel mills ran from roughly 1930 through the early 1980s, with legacy materials remaining in place well into the 1990s and beyond:

  • 1940s–1960s: Post-war steel production expansion drove large-scale construction and equipment installation. Asbestos-containing insulation, gaskets, packing, and refractory materials were standard specifications for virtually all high-temperature applications at the Middletown Works and comparable facilities.

  • 1970s: Despite the Selikoff studies of the 1960s establishing the link between asbestos exposure and mesothelioma, large quantities of asbestos-containing materials reportedly remained in place at the Middletown Works. Maintenance workers allegedly continued daily contact with these materials throughout the decade.

  • 1978–1986: OSHA and EPA regulatory action curtailed new asbestos installation. Existing materials at steel mills throughout the Midwest frequently stayed in place — keeping maintenance and repair workers at ongoing risk.

  • 1986–present: OSHA’s asbestos standards (29 CFR 1910.1001 and 1926.1101) imposed strict requirements for working with asbestos-containing materials, but legacy materials throughout the Middletown plant may have remained potential hazards for any worker who disturbed them during routine maintenance, repair, or renovation.

Part III: Asbestos-Containing Products Allegedly Present at the Middletown Works

Thermal Insulation Products

Pipe and equipment insulation represented one of the largest categories of asbestos use in steel mills. Workers at the Middletown Works may have been exposed to asbestos-containing insulation products from:

  • Johns-Manville Corporation — among the largest asbestos product manufacturers in American history, producing pipe insulation under trade names including Kaylo, along with block insulation, cement products, and thermal insulation systems. Johns-Manville products are documented in comparable integrated steel mills throughout the Midwest.
  • Owens-Corning Fiberglas and Owens-Illinois — asbestos-containing insulation products for high-temperature industrial applications, with widespread documented use in steel mill operations
  • Armstrong World Industries — thermal insulation products and building materials reportedly containing asbestos-containing compounds
  • Celotex Corporation — asbestos-containing insulation and building materials distributed to industrial facilities
  • Eagle-Picher Industries — asbestos-containing insulation and industrial products, including Thermobestos brand thermal insulation reportedly used in high-temperature piping systems
  • W.R. Grace — asbestos-containing insulation products and thermal protection systems
  • Georgia-Pacific — asbestos-containing insulation materials and building products distributed to industrial steelmakers
  • Philip Carey Manufacturing — Magnesia pipe insulation and other asbestos-containing thermal products used in steam systems
  • Unarco Industries — Aircell and asbestos-containing block insulation products for extreme-temperature applications

Legal note: The presence of specific products at the Middletown Works in particular time periods is alleged based on the types of operations conducted there and industry-wide documentation of product use at comparable integrated steel mills. Individual product presence should be confirmed through facility records, employment records, and legal discovery.

Gaskets and Packing Materials

Steel mills run thousands of flanged pipe connections, valve stems, pump shafts, and mechanical joints — each requiring gaskets or packing to prevent leaks of steam, hot water, gases, and caustic fluids. For high-temperature, high-pressure applications, asbestos-containing sealing products were historically the standard specification.

Manufacturers whose asbestos-containing products may have been used at the Middletown facility:

  • Garlock Sealing Technologies — asbestos-containing gaskets and packing, including Cranite and Superex brand sealing products. Garlock has been a defendant in thousands of asbestos cases brought by steel mill workers.
  • Flexitallic Gasket Company — spiral wound gaskets containing asbestos-containing materials for high-temperature piping systems
  • John Crane Inc. — asbestos-containing packing and mechanical seals in pumps, valves, and rotating equipment
  • Durco / Durametallic — packing and seal products for steel mill pump and valve applications
  • A.W. Chesterton Company — asbestos-containing packing products commonly used by millwrights and pipefitters during maintenance and repair

Refractory and Furnace Materials

Blast furnaces, coke ovens, basic oxygen furnaces, ladles, and tundishes at the Middletown Works required refractory materials — many of which historically allegedly contained asbestos-containing compounds:

  • Refractory cement and castables — used to line and repair furnace walls, doors, and hearths
  • Ceramic fiber products — furnace insulation, some earlier formulations allegedly containing asbestos
  • Asbestos-containing refractory board — furnace doors, covers, and heat shields
  • Asbestos rope and tape — sealed furnace doors and provided flexible insulation at joints and penetrations

Manufacturers of asbestos-containing refractory products whose materials may have been present at the Middletown Works:

  • Combustion Engineering — refractory and furnace systems for steel mill operations
  • Harbison-Walker Refractories — refractory product line, many formulations historically allegedly containing asbestos-containing materials
  • A.P. Green Industries — refractory materials and furnace components
  • General Refractories Company — refractory products distributed to steel mills throughout the Midwest

Boiler and Turbine Products

The steam and power generation systems at the Middletown Works required extensive insulation and sealing. Workers may have been exposed to asbestos-containing materials including:

  • Boiler block insulation — preformed asbestos-containing sections applied to boiler surfaces, regularly removed and replaced during maintenance
  • Turbine insulation blankets — custom-fabricated asbestos-containing covers for steam turbines
  • Boiler rope and gaskets — asbestos-containing products sealing boiler doors, handhole covers, and pressure vessel penetrations
  • Steam trap components — asbestos-containing internal components in steam traps used throughout the facility
  • Insulation products under trade names including Unibestos and Monokote, reportedly used in high-temperature industrial boiler and turbine applications at facilities of this type

Flooring and Building Materials

The buildings at the Middletown Works reportedly contained asbestos-containing materials well beyond equipment insulation:

  • Vinyl floor tile — commonly 9"×9" tiles from Armstrong World Industries and other manufacturers, widely installed in office and facility areas through the 1970s
  • Ceiling tiles — asbestos-containing acoustic materials including Gold Bond brand products
  • Asbestos cement board and fireproofing — may have included Pabco and comparable materials used to fireproof structural steel and create fire-rated partitions
  • Roofing materials — asbestos-containing shingles and sheets
  • Spray fireproofing — asbestos-containing coatings applied to structural steel members throughout the facility

Friction Products: Brake and Clutch Components

Brake linings, clutch facings, and other friction products used in industrial equipment at the Middletown Works may have contained asbestos-containing materials from manufacturers including:

  • Raybestos-Manhattan — asbestos-containing brake and clutch products for industrial equipment
  • Bendix Corporation — friction products used in overhead cranes, hoists, and industrial machinery
  • Carlisle Companies — asbestos-containing friction materials for heavy industrial applications

Workers who serviced overhead cranes, material handling equipment, and industrial vehicles may have been exposed to asbestos-containing dust when replacing worn brake and clutch components — work that could place fiber-laden dust directly in the breathing zone.
