WebbBeing very narrow, they are severely attacked by the corrosion current produced by the cathodic reactions over the rest of the metal surface. Such a specific corrosion is commonly called weld decay, because during welding such a temperature range is attained at some distance away from the weld. WebbIntergranular corrosion (IGC) is a form of localized corrosion characterized by preferential corrosion at grain boundaries or areas adjacent to them, with little or negligible attack on …

Webb13 feb. 2024 · Solidification cracking has been a serious problem in austenitic stainless steels. Since solidification cracking often occurs at the solidification grain boundary, the grain boundary character distribution (GBCD) in the weld metal may affect the solidification cracking susceptibility. On the other hand, the columnar grains of the weld metal are … WebbIn order to control the sensitization of the heat-affected zone, use. (1) 304L or 316L grade, because lower carbon content decreases the carbide precipitation. (2) 347 or 321 stabilized grade, because stronger carbide-forming elements (Nb or Ti) prevent the precipitation of chromium carbides. (3) postweld solution annealing treatment in the ...
