Ferrochrome (FeCr) is an alloy used primarily in the production of stainless steel and tool steel. It is produced in an electric arc furnace from Chrome Ore. Ferrochrome is primarily chrome and iron but contains other trace elements of importance such as carbon and phosphorus. The level of carbon concentration will define the grade of ferrochrome.
- High Carbon > 6%
- Low Carbon < 0.5%
- Medium Carbon > 0.5 to < 2%
For a complete listing of ferrochrome specifications, see ASTM A101.
How Our Ferrochrome Analysis Works
McCreath Laboratories will send trained, experienced technicians to take a represented sample for you. Whether in bulk or containers, our technicians have the training, tools and experience to collect a representative sample, ensuring that all subsequent laboratory testing is accurate and reliable. With our mobile crushing units, high carbon and charge chrome in lump form can be partially processed on-site per the ISO and ASTM standards, increasing efficiency and reducing the amount of material taken off-site.

Verification With McCreath Labs
McCreath Laboratories will employ both classical and advanced in-house techniques in the analysis of ferrochrome to ensure the quality of your materials. The techniques have been verified through the use of certified reference materials and some are adopted directly from ASTM or ISO standards. A typical ferrochrome analysis would be done as follows:
|Cr||Titration||Metrohm Titrando||ASTM E363|
|C||Combustion||LECO CS 744||ASTM E1019|
|S||Combustion||LECO CS 744||ASTM E1019|
|P||ICP||Thermo ICAP||In house|
|Si||Gravimetric/ICP||Thermo ICAP||In house|
|N||Inert Gas Fusion||LECO TC 600||ASTM E1019|
|B||ICP||Thermo ICAP||In house|
