Ferro Chrome is an alloy of chromium and iron containing between 50% and 70% chromium. The ferro chrome is produced by electric arc melting of chromite and chromium ore. Most of the world's Ferro Chrome is produced in South Africa, Kazakhstan and India, which have large domestic chromite resources.
The production of steel is the largest consumer of Ferro Chrome, especially the production of stainless steel with a chromium content of between 10 and 20%.
Ferro Chrome with chrome content below 56% is known as 'charge chrome' and produced from a chrome containing ore with a lower chrome content. Alternatively, High Carbon Ferro-Chrome produced from higher grade ore, 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.
