Abstract
The cracking behavior of 2205 duplex stainless steels (DSSs) in synthetic sea water under cathodic polarization condition was investigated. (SSRT) method was employed in aim to evaluate the susceptibility to hydrogen assisted cracking. The results showed that the reduction in the uniform elongation (UEL) and the reduction of area (RA) varied with the applied cathodic current density. Significant reductions in ductility were found, indicating its susceptibility to hydrogen-assisted fracture at current density of 10 mA cm−2. Fractographical examinations showed that increase in hydrogenation current density cause an increase in brittle character on the fracture surface. Complete brittle fractures were observed after SSRT at10 and 20 mA cm−2.
