CA 2407591

A method of enhancing the corrosion resistance of an austenitic steel includes removing material from at least a portion of a surface of the steel such that corrosion initiation sites are eliminated or are reduced in number relative to the number resulting from processing in a conventional manner. Material may be removed from the portion by any suitable method, including, for example, grit blasting, grinding and/or acid pickling under conditions more aggressive than those used in conventional processing of the same steel.

La présente invention concerne un procédé permettant de renforcer la résistance à la corrosion d'un acier austénitique. En l'occurrence, on procède par enlèvement de matière d'au moins une partie d'une surface de l'acier de façon à supprimer ou réduire le nombre de sites de naissance de la corrosion par rapport au nombre de site après traitement conventionnel. L'enlèvement de matière de la partie considérée peut se faire selon tout procédé approprié, et notamment par projection de limaille, par meulage et/ou par attaque à l'acide dans des conditions d'agressivité supérieures à celles du traitement conventionnel du même acier.
