Popis: A method was developed to measure the degree of sensitisation to intergranular corrosion. This electrochemical reactivation test is fast, non-destructive and quantifies the degree of sensitisation. The test measures the current after reactivation associated with the corrosion of chromium depleted regions. This test was carried out on a stabilised and on a not stabilised steel grade in various heat treatment conditions. The test procedures and the results of the test, which have been verified by a metallographical examination, are presented in this study in comparison to results from conventional tests.
