Coshocton Works is Cleveland-Cliffs' stainless steel plant in Coshocton, Ohio. The company describes the site as stainless finishing operations in 570,000 square feet of floor space, and says it produces flat-rolled stainless in austenitic 300- and 200-series, ferritic 400-series, martensitic and precipitation-hardening grades. In 2025 the plant added a $150 million vertical stainless bright anneal line that runs in a 100 percent hydrogen atmosphere with a hydrogen recovery unit. Cleveland-Cliffs is the parent company, and its CEO says the stainless business has been its most consistent profit generator since the 2020 acquisition of AK Steel.
Overview
Cleveland-Cliffs marked the start of a new US$150 million bright anneal line at Coshocton Works in July 2025. The vertical line uses a 100 percent hydrogen atmosphere in place of conventional acid-based processing. A hydrogen recovery unit recycles hydrogen, and the process runs on a 50/50 mix of new and used hydrogen. The company says the line will supply premium stainless for high-end automotive and critical appliance applications, and the chairman and CEO Lourenco Goncalves said it would improve quality and productivity with an expected quick payback.
