Ferro Chrome and Utilize of Ferro Chrome

Ferrochrome is a kind of ferroalloy of which the main content is chromium and iron. And it generally contains 50 to 70% chromium by weight.

Most of the global output of ferro chrome is produced in South Africa, Kazakhstan and India, which have large domestic chromite resources. In recent years, ferro chrome from Russia and China are increasing. Production of steel, especially that of stainless steel with chromium content of 10 to 20%, is the largest consumer and the main application of ferrochrome.

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. 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. Ferro Chrome from South Africa, known as "charge chrome" and produced from a Cr containing ore with a low carbon content, is most commonly used in stainless steel production. Alternatively, high carbon FeCr produced from high-grade ore found in Kazakhstan (among other places) is more commonly used in specialist applications such as engineering steels where a high Cr/Fe ratio and minimum levels of other elements (sulfur, phosphorus, titanium etc.) are important and production of finished metals takes place in small electric arc furnaces compared to large scale blast furnaces. In the past, Ferrochrome alloys were used in the formulation of Type III Compact Cassettes.
