Abstract

The pitting resistance of AISI 316L stainless steel (SS) weld metal in as-deposited and aged conditions was evaluated by determining the critical pitting potential in an acid chloride solution. The results indicated that after aging at 773, 873, or 973 K, the pitting corrosion resistance of the weld metal had deteriorated. The decrease in the critical pitting potential upon aging has been discussed in terms of precipitation of the various secondary phases.
