Stress corrosion cracking mechanism of AISI 316LN stainless steel rebars in chloride contaminated concrete pore solution using the slow strain rate technique

In this work, the stress corrosion cracking (SCC) mechanism of austenitic stainless steel AISI 316 LN rebar is studied along the entire stress-strain diagram by slow strain rate technique. The growth and passivity breakdown of the passive film is proved by non-destructive electrochemical tests as well as by current monitoring. The current density experiences multiple peaks related to the nucleation of metastable pits on AISI 316 LN surface near...
