Cleveland-Cliffs and USW Reach Tentative Labor Agreements

About this Location

Butler Works is located in western Pennsylvania, a one-hour drive north of Pittsburgh. The facility produces stainless and electrical carbon steel. Melting takes place in an electric arc furnace (EAF) that feeds an argon-oxygen decarburization unit for specialty steels. A ladle metallurgy furnace feeds two double-strand continuous casters. The buildings housing electrical-and-stainless-steel melting and casting, hot-roll, cold-roll and finishing operations measure 3.5 million square feet.

Products

Butler Works is a leading producer of flat-rolled electrical and stainless steels and a supplier of stainless and carbon semi-finished slabs.

  • TRAN-CORĀ® is the only high-permeability electrical steel made in the United States, used in power transformers.
  • Regular Grain-Oriented (RGO) products are used for power and distribution transformers. Cleveland-Cliffs is the only producer of this in the United States.
  • Cold Rolled Non-Oriented (CRNO) grades are used primarily in electric motors, generators, and lighting ballasts. Ferritic (Chrome) grades are used in applications that need to withstand extreme heat and corrosive conditions.
  • Chrome Austenitic (Nickel) grades of stainless steel are designed for applications that demand extraordinary strength, durability, and corrosion resistance.
  • Carbon Slabs are produced on one of the two dual-strand casters. Butler Works can produce ultra-low sulfur steel, which is beneficial for many carbon steel applications, including Advanced High Strength Steels (AHSS). These slabs are then finished at Cleveland-Cliffs' other manufacturing plants.
