Resumo
Duplex stainless steels have been widely used in the manufacture of equipment
and piping for different segments, such as chemical, pulp & paper and oil & gas.
The major limitation of these steels is the precipitation of deleterious phases
whenever they are exposed to high temperatures. This fact drastically reduces the
corrosion resistance and mechanical properties of these materials. The friction
stir welding (FSW) has been considered an alternative to replace fusion welding
processes. FSW is a solid state welding process avoiding many of the weldability
problems associated to conventional fusion techniques. In this paper, the
corrosion resistance of friction stir welded lean duplex grade 2404 (UNS S82441)
was evaluated by cyclic potentiodynamic polarization and critical pitting
temperature (CPT) in Cl- containing media . The results indicated that for the
conditions adopted the FSW process did not have a significant effect on the
pitting corrosion resistance of the steel studied.
