摘要

This work discusses on-site use of Double Loop Electrochemical Potentiodynamic Reactivation Technique (DL-EPR) for Duplex Stainless Steel. It is suggested that instead of altering the standard parameters for each different material tested, the procedure adopted is to determine in laboratory all the parameters for a specific material tested beforehand and then use those results as standard criteria to be compared with the results obtained on-site. Analysis is performed at two commercial super-duplex steels, UNS S 32750 and UNS 32760 and in steel 22Cr6Ni2Mo with low nitrogen content. Then, a welded joint of UNS S 32750 steel is analysed.
