Abstract Scope The objective of this presentation is to understand the effects of local stress and grain boundary (GB) type on chloride-induced stress corrosion cracking (CISCC) growth in austenitic stainless steel (AuSS). CISCC likely occurs transgranularly (TGSCC), and thus propagates through localized slip and dislocation pile-up at grain boundaries in AuSS. However, its propagation criteria are not well known. In this study, 304L SS specimens are loaded in tension in four-point bend fixtures and corroded in boiling magnesium chloride. The GB types and characters along the crack paths are characterized using scanning electron microscopy with electron backscatter diffraction (EBSD). Local stresses at specific GB positions are simulated by finite element analysis to inform the effect of stress on cracking behaviors at different GB types. These results will be discussed in the context of previously proposed TGSCC propagation criteria. SNL is managed and operated by NTESS under DOE NNSA contract DE-NA0003525. SAND2021-7896A.
