Additional information
Black liquor is likely to be corrosive to metals and classification is required. The classification concerning corrosivity is assigned based on information from the manufacturers of Black liquor.
In the study by Keiser & al. (2003) it was concluded that cracking was most likely due to polythionic acid stress corrosion cracking. Therefore a stabilized stainless steel was recommended or a low carbon grade should be used in the future applications when sulfidizing gases were expected to be present.
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.
