Iron and Steel Mills and Ferroalloy Manufacturing

Parent Code 33111

Implementation Date 2022-01-01

Industry Description

This industry comprises establishments primarily engaged in one or more of the following: (1) direct reduction of iron ore; (2) manufacturing pig iron in molten or solid form; (3) converting pig iron into steel; (4) making steel; (5) making steel and manufacturing shapes (e.g., bar, plate, rod, sheet, strip, wire); (6) making steel and forming pipe and tube; and (7) manufacturing electrometallurgical ferroalloys. Ferroalloys add critical elements, such as silicon and manganese for carbon steel and chromium, vanadium, tungsten, titanium, and molybdenum for low- and high-alloy metals. Ferroalloys include iron-rich alloys and more pure forms of elements added during the steel manufacturing process that alter or improve the characteristics of the metal.

Excludes

Operating coke ovens--are classified in U.S. Industry 324199, All Other Petroleum and Coal Products Manufacturing; Manufacturing nonferrous superalloys, such as cobalt or nickel-based superalloys--are classified in U.S. Industry 331492, Secondary Smelting, Refining, and Alloying of Nonferrous Metal (except Copper and Aluminum); Manufacturing concrete reinforcing bar by rolling and drawing steel from purchased steel--are classified in U.S. Industry 331221, Rolled Steel Shape Manufacturing; and Manufacturing fabricated structural metal products from concrete reinforcing bars and fabricated bar joists--are classified in U.S. Industry 332312, Fabricated Structural Metal Manufacturing.
