Ferrochrome - Wikipedia
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 carbon content, is most commonly used in stainless steel production.

Chromium processing | Britannica
Chromium processing, preparation of the ore for use in various products. Chromium (Cr) is a brilliant, hard, refractory metal that melts at 1,857 °C (3,375 °F) and boils at 2,672 °C (4,842 °F). In the pure state it is resistant to ordinary corrosion, resulting in its application as an electroplated
Balasore Alloys : Production Process
Production Process. Ferrochrome (FeCr) is a corrosion-resistant alloy of chrome and iron containing between 50% and 70% chrome. Ferrochrome production is essentially a carbothermic reduction operation taking place at high temperatures. Cr Ore, an oxide of chromium and iron, is reduced by coal and coke to form the iron-chromium alloy.
