Mercer County’s industrial heart was the Shenango Valley, and the valley’s biggest name was Sharon Steel. Its main works sat in Farrell, the town originally laid out as South Sharon around the mills, and steel was made there for most of the twentieth century before the company passed through bankruptcy in the late 1980s and operations wound down in the early 1990s. Those decades of steelmaking coincide with the era when asbestos was standard in industrial insulation, which is why Sharon Steel names keep appearing in Pennsylvania mesothelioma cases.
A valley built on hot metal
Sharon Steel ran integrated operations, from iron and steelmaking through rolling and finishing, and the surrounding boroughs of Sharon, Farrell, and Hermitage supplied its workforce for generations. The company’s later corporate history was turbulent, but the day-to-day reality inside the mills changed little: furnaces, soaking pits, rolling mills, and a network of insulated steam lines connecting all of it.
The valley had a second major industrial employer in Westinghouse, whose Sharon plant built transformers for decades. Electrical equipment manufacturing brought its own asbestos-era materials, from insulated heat sources to heat-resistant components, so a Shenango Valley work history often includes both employers.
Where the asbestos was
The National Cancer Institute reports that asbestos was the standard material for insulating boilers, pipes, furnaces, and similar high-heat equipment until the late 1970s (NCI asbestos fact sheet). In the Sharon Steel works that meant pipe covering and block insulation on steam systems, refractory and heat-resistant materials around furnaces, gaskets and packing in valves and pumps, and asbestos cloth in gloves and aprons for hot-metal crews. Maintenance, repair, and reline work put fibers in the air, and everyone in the building shared that air.
Valley jobs that carried exposure
- Open hearth, furnace, and melt shop crews
- Rolling mill and finishing hands near insulated equipment
- Pipefitters, millwrights, bricklayers, and boiler house crews
- Westinghouse Sharon production and maintenance workers
- Laborers on tear-out and cleanup assignments
The regional picture
Shenango Valley men often ranged across western Pennsylvania and eastern Ohio for work, and their histories connect to the wider mill belt: Crucible Steel in Midland down the Beaver valley, and the J&L Aliquippa Works on the Ohio. Every additional site in a work history can add product manufacturers to a claim. The Pennsylvania asbestos exposure sites index covers the rest.
Bankrupt employer, live claim
Sharon Steel’s bankruptcy does not close the door, because the employer was never the main target. Claims proceed against the companies that made and supplied the asbestos products used in the mills, and many of those manufacturers now pay through dedicated bankruptcy trusts. Pennsylvania generally allows two years from the date of diagnosis to file (42 Pa. C.S. § 5524), and mesothelioma’s 20 to 50 year latency, per the NCI, means diagnoses tied to the valley’s working decades are still arriving.
Rebuilding a Shenango Valley work history is document work, and the documents still exist: Social Security earnings statements listing every employer year by year, steelworker and electrical union records, pension files, and the recollections of co-workers. Depositions from earlier valley cases describe the products used in these plants, so a new claim rarely starts from zero. Families should write down what they know now, while names and years are still within reach. Even a single remembered detail, a department name or a foreman, can anchor the rest.
What this means for your family
What a family knows is usually simple: he worked at Sharon Steel from the 1960s until the end, or she worked at Westinghouse and washed his mill clothes besides. That is a real starting point. Matching those years to the specific departments, products, and responsible companies is the lawyer’s job, done through litigation records built over decades. Michael C.
