Corrosion des métaux et alliages — Méthode d'essai de gravure à l'acide oxalique pour la corrosion intergranulaire de l'acier inoxydable austénitique

This document specifies a method to test for intergranular corrosion (IGC) in austenitic stainless steels using an oxalic acid etch. This method can evaluate non-sensitization of austenitic stainless steels by observing the structure of the etched surface with a microscope after performing electrolytic etching (hereinafter called “etching”) on austenitic stainless steel in an oxalic acid solution.
