Over 80% of the world's ferrochrome is utilised in the production of stainless steel. In 2006, 28,000,000 tons of stainless steel were produced. [3] [4] Stainless steel depends on chromium for its appearance and resistance to corrosion. Average chrome content in stainless steel is approx. 18%. It is also used to add chromium to carbon steel ...
Ferroalloys are used as deoxidizers and alloy additives in the steel manufacturing process. The ferromanganese plant started production in 1957, equipped with three furnaces for production of high carbon ferromanganese and ferrosilicon. In 1969, a reduction furnace and a slag furnace were commissioned for the production of ferrochrome. The ...
Steel is made from iron and carbon. Cast iron is a hard, brittle material that is difficult to work, whereas steel is malleable, relatively easily formed and versatile. On its own, iron is not strong, but a low concentration of carbon – less than 1 percent, depending on the kind of steel – gives steel strength and other important properties.
Silicon ferroalloy consumption is driven by cast iron and steel production, where silicon alloys are used as deoxidizers. Some silicon metal was also used as an alloying agent with iron. On the basis of silicon content, net production of ferrosilicon and miscellaneous silicon alloys in the US was 148,000 t in 2008.
Chromite today is mined particularly to make stainless steel through the production of ferrochrome (Fe Cr), which is an iron-chromium alloy. [8] Chromite grains are commonly found in large mafic igneous intrusions such as the Bushveld in South Africa and India.

The main differences in composition, when compared with austenitic stainless steel is that duplex steels have a higher chromium content, 20–28%; higher molybdenum, up to 5%; lower nickel, up to 9% and 0.05–0.50% nitrogen. Both the low nickel content and the high strength (enabling thinner sections to be used) give significant cost benefits.
