标准摘要
[中文适用范围]： 本文件规定了一种使用草酸蚀刻法检测奥氏体不锈钢晶间腐蚀 (IGC) 的方法。该方法通过在草酸溶液中对奥氏体不锈钢进行电解蚀刻（以下称为“蚀刻”）后用显微镜观察蚀刻表面的结构，可以评估奥氏体不锈钢的非敏化性。 [外文原描述]： 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.
