331112  Electrometallurgical Ferroalloy Product Manufacturing US

 

This U.S. industry comprises establishments primarily engaged in 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 being made.

 

Cross-References. Establishments primarily engaged in--

• Manufacturing electrometallurgical steel and iron-based superalloys--are classified in U.S. Industry 331111, Iron and Steel Mills; and

• 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).
