HI CARBON (HC) FERRO CHROME
DESCRIPTION
 |
Ferro Chrome (FeCr) is an alloy of chromium and iron containing between 50% and 70% chromium. The Ferro Chrome is produced by electric arc melting of chromite, an iron magnesium chromium oxide and the most important chromium ore. Most of the world's Ferro Chrome is produced in South Africa, Kazakhstan and India, which have large domestic chromite resources. Increasing amounts coming from Russia and China. The production of steel is the largest consumer of Ferro Chrome, especially the production of stainless steel with chromium content of 10 to 20% is the main application of Ferro Chrome.
Over 80% of the world's Ferro Chrome is utilised in the production of stainless steel. In 2006 28 Mt of stainless steel were produced. Stainless steel depends on chromium for its appearance and its resistance to corrosion. The average chrome content in stainless steel is approximately 18%. It is also used when it is desired to add chromium to carbon steel. FeCr from Southern Africa, known as 'charge chrome' and produced from a Cr containing ore with a low Cr 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 to Fe ratio and minimum levels of other elements such as Sulfur, Phosphorus and Titanium are important and production of finished metals takes place in small electric arc furnaces compared to large scale blast furnaces.
