Automobile sales help AK Steel's business keep rolling, though it also has operations in the infrastructure and manufacturing industries. The company manufactures carbon, stainless, and electrical steel. It sells hot- and cold-rolled carbon steel to construction companies, steel distributors and service centers, and automotive and industrial machinery producers. AK Steel also sells cold-rolled and aluminum-coated stainless steel to automakers. The company produces electrical steels (iron-silicon alloys with unique magnetic properties) for makers of power transmission and distribution equipment.
