Mercer County’s industrial heart was the Shenango Valley, and the valley’s biggest name was Sharon Steel. Its main works sat in Farrell, a town first laid out as South Sharon around the mills. Steel was made there for most of the twentieth century. The company later went bankrupt, and its operations ended in the early 1990s, though the plant continued under new owners. Those decades of steelmaking overlap with the era when asbestos was a standard industrial insulation. That is why Sharon Steel keeps appearing in Pennsylvania mesothelioma cases.

Shenango Valley Steel Mills and Their Workforce

Sharon Steel ran large-scale operations, from making iron and steel through rolling and finishing. Families in Sharon, Farrell, and the surrounding communities that later became Hermitage supplied its workforce for generations. The company’s corporate history was turbulent, but daily life inside the mills changed little. Workers spent their days among furnaces, soaking pits, rolling mills, and a web of insulated steam lines connecting them all.

The valley’s other major employer was Westinghouse, whose Sharon plant built electrical transformers for decades. Electrical equipment manufacturing used its own asbestos-era materials, including insulation around heat sources and heat-resistant components. As a result, many Shenango Valley work histories include both employers.

Asbestos Products Used at Sharon Steel

According to the NCI asbestos fact sheet, asbestos was widely used for decades to insulate boilers, pipes, furnaces, and other high-heat equipment. Inside the Sharon Steel works, that likely meant:

  • Pipe covering and block insulation on steam systems
  • Refractory and heat-resistant materials around furnaces
  • Gaskets and packing in valves and pumps
  • Asbestos cloth gloves and aprons for hot-metal crews

Maintenance, repair, and furnace relining put fibers into the air. Everyone working nearby breathed that same air, whatever their job title.

Sharon Steel and Westinghouse Jobs With Asbestos Exposure Risk

  • Open hearth, furnace, and melt shop crews
  • Rolling mill and finishing workers near insulated equipment
  • Pipefitters, millwrights, bricklayers, and boiler house crews
  • Westinghouse Sharon production and maintenance workers
  • Laborers on tear-out and cleanup assignments

Western Pennsylvania and Ohio Mill Belt Asbestos Sites

Shenango Valley workers often traveled across western Pennsylvania and eastern Ohio for work. Their histories frequently connect to the wider mill belt, including Crucible Steel in Midland and the J&L Aliquippa Works, both on the Ohio River. Each additional job site in a work history can add product manufacturers to a claim. The Pennsylvania asbestos exposure sites index covers other locations across the state.

Filing a Mesothelioma Claim After the Sharon Steel Bankruptcy

Sharon Steel’s bankruptcy does not end a family’s options, because the employer was rarely the main target. Claims usually proceed against the companies that made and supplied the asbestos products used in the mills. Many of those manufacturers now pay through dedicated asbestos bankruptcy trusts.

Pennsylvania sets filing deadlines, so families should act promptly after a diagnosis. According to the NCI, asbestos-related disease often appears decades after exposure. That means diagnoses tied to the valley’s working years are still appearing today.

Rebuilding a Shenango Valley work history takes paperwork, and much of it still exists. Useful sources include Social Security earnings statements listing employers by year, steelworkers’ and electrical union records, pension files, and the memories of former coworkers. Testimony from earlier valley cases also describes products used in these plants, so a new claim rarely starts from scratch. Families should write down what they remember now, while names and dates are still within reach. Even one detail, such as a department name or a foreman, can help anchor the rest.

Help for Sharon, PA Mesothelioma Patients and Families

What a family knows is often simple. He worked at Sharon Steel for most of his career. She worked at Westinghouse and washed her husband’s mill clothes at home. That is a real starting point. Matching those years to specific departments, products, and responsible companies is the lawyer’s job, using litigation records built up over many years.
