Corrosion Performance of Girth-Weld Joints of Duplex Stainless Steels
Source abstract
Abstract
The corrosion resistances of the girth-weld heat-affected zone (HAZ) of duplex stainless steels were discussed regarding their use in pipeline for hostile environments. A girth-welded HAZ with a slow cooling rate welding procedure and a high-pitting-index base metal (Cr + 3Mo + 16N = 34) showed the same corrosion resistance as the base metal, even in the as-welded condition. The effect of the slow cooling rate would result from enough time for chromium to heal the chromium depleted area adjacent to chromium nitride precipitates.
