ER 308Lwas utilized as the filler metals for the groove and overlay welds of a 304L stainless steel (SS) substrate, which was prepared via a gas tungsten arc-welding process in multiple passes.U-bend and weight-loss testswere conducted by testing the SS substrate and welds in a saltspray containing 10 wt% NaCl at 80℃ to evaluate their stress corrosion cracking (SCC) susceptibility.Under the same specimen preparation, the weight loss of the ER 308 deposits was higher than the base metal (BM) in a salt spray.The dissolution of the skeletal structure in the fusion zone (FZ) was responsible for the greater weight loss of the 308 deposits,especially for the cold-rolled and sensitized specimen.Cold rolling and/or sensitization were harmful to the SCC resistance of the 304 SS plate and weld.Overall, the SCC susceptibility was related with the weight loss of the specimen in each group.
