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.","examples":[],"notes":[],"history_note":null,"editorial_note":null,"in_scheme":null,"identifier":null,"description":null,"source":null,"country":null}
