The data presented was developed through analysis of EBSD datasets of SCC cracks taken from active low carbon steel pipelines. Samples were analysed on an FEI Inspect F50 SEM with an EDAX Hikari EBSD detector using OIM Data Collection 7 and analysed using OIM Analysis 7. Samples were obtained from the ND-TD plane to capture the morphology of the cracks and the resulting dataset rotated in software by 90 degrees about the TD direction to align the orientation of the sample to that of the system. The data contains information of grain boundary characteristics exported from standard OIM Analysis functions as well as some mechanical properties conducted on the sectioned steel samples.
