Bars were tested both before and after undergoing mechanical straightening. Based on the test results, the stainless steel bars satisfy the requirements of ASTM A955-12. The straightening process allowed corrosion to initiate on the bars, but had limited to no effect on the macrocell corrosion rate.ChloridesConcreteCorrosionMacrocellReinforcing steelStainless steelTechnical Reporthttps://orcid.org/0000-0001-5039-3525openAccess
