Ferrochrome (FeCr)
is a corrosion-resistant alloy of chrome and iron with a chrome content
of between 50% and 65% chrome and a finished material which contains
about 50-70% chromium alloyed with iron – though this depends on the
ore used by the producer.
Ferrochrome
Pricing
We source our ferrochrome
from producers in China and India. The
product is priced in terms of the weight of chrome; for example 1 tonne
of Fe-Cr65, with a chrome content of 65% will be sold on the basis of
0.65 tonnes of Chrome, expressed in US cents per lb of Chrome.

Ferrochrome
Production
Most of the world's ferrochrome
is produced in South Africa, Kazakhstan and India, all which have large
domestic Chromium Ore resources. Increasing amounts are coming from
Russia and China.
Like many
ferroalloys,
ferrochrome
is utilised in the production of stainless steel – around 80% of the
world’s ferrochrome is used in this way - as stainless steel depends on
chrome for its appearance and its resistance to corrosion. The average
chrome content in stainless steel is approximately 18%. Ferrochrome is also
used to add chromium to carbon steel.FeCr
from Southern Africa is known as 'charge chrome' and is produced from a
chrome containing ore with a low chrome content. It is most commonly
used in stainless steel production, whereas High Carbon Ferrochrome
produced from high grade ore found in Kazakhstan is more commonly used
in specialist applications such as engineering steels. Here, a high Cr
to Fe ratio and minimum levels of other elements such as Sulphur,
Phosphorus and Titanium are important. The production of finished
metals takes place in small electric arc furnaces.
The
vast majority of FeCr
produced is charge chrome from Southern Africa. With high carbon being
the second largest segment followed by the smaller sectors of low
carbon and intermediate carbon material.
