Abstract

An austenitic stainless steel (AISI 304) pipe weldment, which had been in operation about 45,000 h at 230°C in the Ringhals 1 BWR plant, was characterized using electrochemical sensitization testing methods (electrochemical potentiokinetic reactivation [EPR] and double-loop EPR), as well as transmission electron microscopy. The weld heat-affected zone (HAZ) showed a sensitized zone between two and five mm from the fusion line in which grain boundary carbides formed almost a continuous chain, and Cr-depletion was evident.
