High Carbon Ferrochrome
Ferrochrome is a corrosion-resistant alloy of chrome and iron with a chrome content of between 50% and 60%. Maranatha produces high carbon ferrochrome with a range of Cr 57 to 60%.
Ferrochrome (FeCr) is often classified by the amount of carbon and chrome it contains. 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.
High Carbon Ferrochrome is an alloy with the following typical specifications.
| Chrome content (Cr) |
- 50 - 60% |
Carbon (C)
|
- 6 - 8% |
| Silicon (Si) |
- 3.0% max |
| Manganese (Mn) |
- 0.3% max |
| Sulphur (S) |
- 0.06% max |
Phosphorous (P)
|
- 0.03% max |

Product Uses
- Most of HCFC is used as a feed in the production of stainless steel where it is present at a minimum concentration of 11.5%, but can go as high as 30%
- HCFC is used in a variety of Alloy Steels, Cast Irons and Non-Ferrous Super Alloys.
- It also has significant chemical and refractory uses.
- Typically, high carbon ferrochrome is used to enhance steel’s hardness, creep and impact strengths and resistance to corrosion and oxidation.
Pricing: Prices of ferrochrome are often quoted in terms of United States cents (¢) per pound (lb) of chrome contained, although producing companies will generally report production and sales in terms of metric tonnes Fe Cr sold. Historically high carbon ferrochrome prices have been set on a quarterly basis.
