Targets of this work have been: testing of duplex stainless steel in field (into a geothermal well) and in laboratory NACE environment in presence of crevices and sharp defects; development of testing based on fracture mechanics and comparsion with traditional testing approach. The following types of specimens have been used: smooth specimens for tensile tests at constant load with artificial crevices, U‐bend specimens and 1/2″ WOL‐modified fracture mechanics specimens. The results are only in partial accordance with available literature data and suggest to be very careful in extending laboratory results to real conditions, where, for instance, crevices and sharp defects always exist.
