Title (EN) USE OF NITROGEN COMPOUNDS IN THE PICKLING OF STAINLESS STEEL
(FR) UTILISATION DE COMPOSÉS AZOTÉS POUR LE DÉCAPAGE D'UN ACIER INOXYDABLE
Abstract: front page image
(EN)The present invention relates an acidic aqueous solution suitable for the pickling of stainless steel grades that comprises accelerators based on watersoluble inorganic compounds comprising at least one nitrogen atom in an oxidation state in the range of -2 to -1/3. The present invention further encompasses a process for the pickling of stainless steel that makes use of a pickling solution comprising the above-mentioned accelerators.
(FR)La présente invention concerne une solution aqueuse acide appropriée pour le décapage de grades d'acier inoxydable, qui comprend des accélérateurs à base de composés inorganiques hydrosolubles contenant au moins un atome d'azote dans un état d'oxydation compris dans la plage allant de -2 à -1/3. La présente invention concerne en outre un procédé de décapage d'un acier inoxydable qui utilise une solution de décapage comprenant les accélérateurs susmentionnés.
