Causes and Prevention of Corrosion on Welded Joints

Dec 17, 2015· Using a low-carbon stainless steel such as the 304L and 316L, and hence prevent the formation of carbide. Using post-weld heat treatment. Using stabilized grades alloyed with niobium or titanium such as the 347 and 321 respectively. Niobium and titanium are strong carbide-formers that react with carbon and prevent the chromium depletion.
