Armco Steel Middletown Works Armco Steel's Middletown Works was the company's flagship facility and the economic anchor of Middletown, Ohio. The integrated steel mill used asbestos extensively in its blast furnaces, open hearth furnaces, and rolling mill operations, exposing generations of workers to hazardous fibers.
Last verified: 2026-03-09Founded in 1900 by George Verity as the American Rolling Mill Company (ARMCO), the Middletown Works grew into a major steel producer specializing in flat-rolled and specialty steels. The plant was the largest employer in Middletown for most of the 20th century. Armco merged with Kawasaki Steel in 1989 to form AK Steel, which was later acquired by Cleveland-Cliffs. Asbestos was used throughout the facility from its earliest days until regulatory changes in the late 1970s.
Asbestos insulation was used on open hearth furnaces, blast furnaces, soaking pits, and reheat furnaces throughout the Middletown Works. Steam distribution systems running throughout the plant were wrapped in asbestos pipe lagging. Workers performing furnace relining, pipe repair, and general maintenance disturbed asbestos insulation regularly, releasing fibers into the workplace air.
The following job categories at Armco Steel Middletown Works had the highest risk of asbestos exposure:
Former Armco Steel workers from the Middletown Works have reported elevated rates of mesothelioma, lung cancer, and asbestosis. Workers who spent their careers in the plant's hot departments accumulated decades of asbestos exposure. Medical screenings of former employees have detected asbestos-related pleural changes in a significant percentage of those examined.
Health information is based on established medical research on asbestos exposure. Asbestos is classified as a known human carcinogen by the National Cancer Institute, the Agency for Toxic Substances and Disease Registry, and the U.S. Environmental Protection Agency. Consult a physician for medical advice specific to your situation.
Workers exposed to asbestos at Armco Steel Middletown Works may be entitled to compensation through asbestos trust funds, personal injury lawsuits, or veterans benefits. Mesothelioma patients and their families have recovered billions in compensation from companies that manufactured or used asbestos products.
Find Out If You QualifyWorkers who were employed at Armco Steel Middletown Works between 1940s–1970s may have been exposed to asbestos-containing materials. If you've been diagnosed with mesothelioma, lung cancer, or asbestosis, you may have legal options including trust fund claims and lawsuits.

Armco Steel became AK Steel after a 1989 merger with Kawasaki Steel. AK Steel was then acquired by Cleveland-Cliffs in 2020. The Middletown Works continues to operate under Cleveland-Cliffs, though asbestos has been largely removed from the facility.
Workers in the blast furnace, open hearth, and maintenance departments faced the highest asbestos exposure. Insulators, pipe fitters, and boilermakers who directly handled asbestos materials had the most intense contact.
Yes. Because asbestos-related diseases can take 20 to 50 years to develop, many former workers are only now receiving diagnoses. Statutes of limitations typically begin at the time of diagnosis, not the time of exposure. Consult an asbestos attorney to evaluate your case.
No. Missing paperwork is normal after this long, and it is not what decides a claim. A Social Security earnings statement lists every employer you had, by year, and can usually be requested directly. Union records, W-2s and a DD-214 for military service do similar work. Coworkers who were there can also confirm conditions. What matters most is what you remember, written down in your own words.
Yes. A wrongful death claim can be brought by the estate or eligible family members, and it is a separate route from a claim the patient would have brought themselves. It also runs on a different clock: the deadline generally starts at the date of death rather than the date of diagnosis, which means families are sometimes still in time when they assume they are not. Deadlines are set by each state, so confirm the one that applies to yours.
Possibly. Asbestos fibres travelled home on work clothes, in hair and in vehicles, and household members were exposed while washing laundry or greeting someone at the end of a shift. This is called secondhand or take-home exposure and it is a recognised route to a claim in its own right, not an exception. If you are documenting a family member's work history, write down your own contact with their work clothing as well.
You do not need a lawyer, a diagnosis, or a decision to do this. You need a piece of paper. Memory is the part of a claim nobody else can reconstruct for you, and it is the part that fades.
If you are doing this for a relative who has died, write down what you remember too, including work clothes brought home to be washed. Household exposure is a real claim, not an edge case.
That is usually enough to work out which claims are open to you — trust funds, a lawsuit, or VA benefits if the exposure happened in service. You do not need records, dates you are certain of, or the name of a product. If you are asking on behalf of someone who has died, a family member can file and the deadline runs differently. No cost, no obligation, and no pressure to decide anything today.
