- TRAN-COR庐 is the only high-permeability electrical steel made in the United States, which is used in power transformers.
- Regular Grain-Oriented (RGO) products are used for power and distribution transformers. AK Steel 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 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 AK Steel鈥檚 other manufacturing plants.
