Abstract EN
In the present study as in our previous studies (Arikan and Doruk, 2008 and Arikan et al., 2012), similar specimens taken from a hot rolled cylindrical duplex stainless steel (DSS) bar with 22% Cr grade were solution annealed at 1050°C and then aged at 800∘C from 100 to 31622 min for sensitization treatment.
Double loop electrochemical potentiodynamic reactivation and standard weight loss immersion acid tests were conducted.
The solution annealed samples were found unsensitized.
The samples aged for 100 min were less sensitized whereas samples aged for 316 min and more time were sensitized.
The degree of sensitization (DOS) can be attributed to higher contribution of chromium and molybdenum depleted areas that result from intermetallic phases.
However, especially the samples aged from 3162 to 31622 min have revealed chromium replenishment.
Consequently, the degree of sensitization was lowered in comparison to the results obtained in previous studies.
