Resumo: Duplex stainless steels have been widely used in the manufacture of equipment and piping for oil & gas industry, in onshore and offshore service. However, whenever they are exposed to high temperatures the precipitation of deleterious phases might occur. The precipitates drastically reduce the corrosion resistance and mechanical properties of these materials. The friction stir welding (FSW) process has been considered as an alternative to replace the conventional welding processes in duplex stainless steels. FSW is a solid state welding process avoiding many of the problems associated to conventional fusion techniques. In this paper, specimens of the various zones affected and nearby the FSW, specifically the nugget or stir zone (SZ), the heat affected zone (HAZ) and the base metal (BM) of welded lean duplex UNS S82441 had their corrosion resistance evaluated by eletrochemical tests. The results indicated that the HAZ and SZ regions presented similar localized corrosion resistance to that of the BM showing that it is a potential technique for replacing the conventional processes with advantageous corrosion resistance properties.
