Under European regulations, this does not present any danger for transport. While this is a stable material under normal conditions, contact with moisture, acids or oxidizing agents produces metal oxides that can be harmful following prolonged exposure. It is used for manufacturing different types of steel in the form of desulfurizing, eliminating nitrogen bubbles that may form during manufacture and reducing the amount of iron oxide resulting from the production process. Ferromanganeseįerromanganese is an iron alloy obtained during carbothermal reduction, a chemical reaction, with manganese oxide-based minerals. The most common ferroalloys in the industry from the large range available, are ferromanganese, silicomanganese and ferrochrome, which we will explain in more detail below. There are a large number of ferroalloys in existence, depending on whether their main purpose is iron deoxidation or whether other metals are intended to be provided in order to obtain special steels with defined characteristics. And their purpose? These elements are applied to improve their resistance to corrosion as well as to counteract the negative effects of sulphur during the production process. Ferroalloys belong to the iron and steel field, referring to any iron alloy that includes constituent as well as carbon elements that are used in the steel industry to improve their properties, providing them with specific properties depending on the metal that is used in production. As the 21 st century progresses, the iron and steel industry represents one of the most important industries in the secondary sector, thanks to its contribution to the attainment of steels and alloys with an endless array of applications for our everyday life, from tools, household appliance parts to vital vehicle parts such as valves or bearings, to cite a few examples.
