Abstract
The corrosion behaviour of S32101 duplex and 410 martensitic stainless steel was studied through weight loss and potentiodynamic polarization in 1-6Â M HCl solutions. Results show that S32101 steel has significantly lower corrosion rates than 410 steel from both tests at all concentrations with highest values of 0.04586Â mm/y and 0.234Â mm/y in comparison to martensitic steel with corrosion rates of 0.827Â mm/y and 19.84Â mm/y at 6Â M HCl concentration. Micrographs from SEM and EDS analyses showed a less corroded morphology for S32101 steel with fewer pits and slight depletion in the percentage composition of chromium and other alloying elements.
