The intergranular corrosion behaviour of three commercially available austenitic stainless steels of high Mn content have been investigated using the oxalic acid etch test and the double loop electrochemical potentiokinetic reactivation technique. Time-temperaturesensitisation diagrams indicate that replacement of Ni by Mn promotes a significant resistance to intergranular corrosion along with the presence of nitrogen in the alloy.
