Description of key information
The release of metals from chromium, ferrochromium and stainless steel particles in various artificial body fluids were studied in a series of experiments.
Additional information
Metal release from ferrochromium, ferrosilicochromium and stainless steel was studied in a series of publications. The results were compared with release data from pure chromium and iron metals and their oxides, and with the bulk and surface compositions of the alloys. Generally, the release rates were very low, and it was concluded that the the bulk or surface characteristics cannot be used for the prediction of metal release from alloys. Chromium was released as Cr(III) and Cr(VI) could not be detected.
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.
