Our Products
Butler Works is a leading producer of flat rolled electrical and stainless steels as well as a supplier of stainless semi-finished slabs.

Electrical Steels produced at Butler include the only high-permeability electrical steel made in the United States, the patented TRAN-COR® H, used in power transformers.

Our Regular Grain-Oriented products are used for power and distribution transformers. Cold Rolled Non-Oriented (CRNO) grades are used primarily in electric motors, generators and lighting ballasts.

Stainless Steels from Butler include chrome (ferritic) grades used in applications that need to withstand extreme heat and corrosive conditions. Chrome nickel (austenitic) grades of stainless are designed for applications that demand extraordinary strength, durability, and corrosion resistance.

Carbon Slabs produced at Butler are manufactured in a conventional, thick continuous cast. Butler Works can produce ultra low sulfur steel, which is beneficial for many carbon steel applications. The slabs are finished at AK Steel’s other manufacturing plants.

Butler Works has earned IATF 16949 and ISO-9001 certification. The plant is a recipient of several customer quality awards, including a "TOP Operations and Plant Award" by 33 Metalproducing Magazine, which recognizes North American metal plants on the leading edge of competitiveness. Butler Works has also received the "Pennsylvania Governor's Award" for labor-management cooperation.

Safety First and First in Safety
Our safety programs are the most comprehensive in the steel industry. Butler Works has received the Pennsylvania "Governor's Award for Safety Excellence," and awards from the National Safety Council. Butler Works was the first steel plant in the nation to receive OSHA's "Star" safety designation, the highest under the Voluntary Protection Program (VPP).
