Super Austenitic Steel, Welding, Pitting Corrosion, NaBr


Super austenitic stainless steel AISI 904L is the commended material for high corrosion resistance and strength requirements. However when subjected to welding there is a possibility of decrease in corrosion resistance. In the present work, 0.4mm thick AISI 904L steel sheets are square butt welded using pulsed current Plasma Arc welding. Pittingcorrosion. Pitting corrosion test was carried out using linear polarization methodby drawing Tafel plots. Corrosion tests were carried out on weldment consisting both fusion zone and heat affected zone in different normalities of Sodium Bromide (NaBr).
