331110 - Iron and Steel Mills and Ferroalloy Manufacturing

The description for the NAICS Code 331110 - Iron and Steel Mills and Ferroalloy Manufacturing is:

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 Being Made.
