ferrochromium sulphur content

Ferrochrome Wikipedia

Ferrochrome, or ferrochromium (FeCr) is a type of ferroalloy, that is, an alloy of chromium and iron, generally containing 50 to 70% chromium by weight.. Ferrochrome is produced by electric arc carbothermic reduction of chromite.Most of the global output is produced in South Africa, Kazakhstan and India, which have large domestic chromite resources.. Increasing amounts are coming from Russia and
