Abstract : One of the localized forms of attack that results in relatively rapid penetration at small discrete areas is called Pitting. The evaluation of pitting susceptibility of materials has been done by using the critical pitting potential, Epit. Polarization is a very important corrosion parameter by which we can make statements about corrosion rates. In the present work the pitting corrosion behavior of FC 2507 Super duplex Stainless steel weld claddings in NaCl solution were investigated in terms of different heat input conditions by using potentiodynamic polarization measurement. The specimen has the best corrosion characteristics with low heat input, which is the result for the lack of deleterious phases such as sigma and Cr2N and balanced ferrite-austenite proportion.
