Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
FeCr-slag is inorganic mineral material and can be compared to silicate minerals occurring in soil naturally. Potential hazard comes from metals, but there are in highly insoluble because of the FeCr-slag mineralogy. Environmental fate of metals in Ferrochromium slag used in road construction has been studied (Rossi 2005) using MMSOILS 4.0 program. The final conclusions were that metals in FeCr-slag products are highly insoluble and they don’t cause pollution to groundwater. Neither does the water filtrated through FeCr-slag containing layer establish any threat to animals drinking it.
Key value for chemical safety assessment
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
