ISO 4212:2023 Corrosion of metals and alloys - Method of oxalic acid etching test for intergranular corrosion of austenitic stainless steel
standard by International Organization for Standardization, 02/01/2023
Full Description
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.Cart
