High-carbon ferrochrome and charge-grade ferrochrome are used in large quantities as charge for smelting stainless steel (AOD or VOD method) to reduce production costs. Medium and low-carbon ferrochrome are used to produce medium and low-carbon structural steel, carburizing steel, gears, high-pressure blower blades, valve plates, etc.

The charge chrome grade was introduced to differentiate it from the conventional high carbon Fe-Cr (HC Fe-Cr). The second largest produced Fe-Cr ferro-alloy is the HC Fe-Cr which has a higher content of Cr than charge chrome and is being produced from higher grade of the chromite ore.

Foundry-grade ferrochrome containing around 62-66% chromium and almost 5% carbon is used for producing cast irons. 3. Our good quality high carbon ferrochrome is used in the manufacturing of ball-bearing steels, tool steels as well as other alloy steels. 4. Ferrochrome alloy is also used when more chromium is needed to be added to carbon steel.

Ferrochrome (FeCr) is an alloy of chromium and iron containing between 50% and 70% chromium. The Producer od stainless steel & tool steel are the largest consumer of ferrochrome and charge chrome.It is chromium that confers upon stainless steel its remarkable corrosion resistance. Out of the total world chrome ore output about 95% is used to ...

Because the charge chrome production technology permits the use of lower-grade chromite ore, charge chrome was accepted as a suitable alloy for stainless steel production, in response to the depleting resources of high Cr /Fe ratio lumpy chromite ore. High carbon ferrochrome is primarily used in the production of stainless steel.

Ferrochrome. Ferrochrome (FeCr) is an alloy of chromium and iron, generally containing 48 to 70% chromium by weight. It is produced in an electric arc furnace by the reduction of chromite ore. South Africa has the largest reserves of chromite ore and is also the world's largest producer of Ferrochrome with most production being exported to China.

These ores typically have Cr/Fe ratios of 1.5 to 1.6 and result in ferrochrome with a chromium content of 50% to 55% (and recently even below 50%) and carbon content typically between 6% and 8%. Ferrochrome produced from these ores is generally referred to as charge chrome and is often included in the broad category of high carbon ferrochrome.
