摘要

This study investigated how 304L stainless steel, which is utilized in demanding conditions, is affected by its microstructure in terms of its resistance to stress corrosion cracking (SCC). Through carefully regulated mechanical and thermal processing, researchers created samples with a range of microstructures, which they then characterized using XRD, EBSD, and SEM. Under tensile stress, SCC tests were carried out in an acidic chloride solution in accordance with ASTM G30 recommendations. The findings showed that a fine-grained microstructure limited intergranular corrosion and provided better SCC resistance because of a more uniform chromium distribution. On the other hand, by encouraging localized corrosion and fracture formation, coarser grains and chromium carbides at grain boundaries increased the susceptibility to SCC.
