Abstract
Stainless steel 316 was examined for compatibility with the eutectic mixtures of NaClâ¯+â¯Na2CO3 and NaClâ¯+â¯Na2SO4 at 700â¯Â°C and Li2CO3â¯+â¯K2CO3â¯+â¯Na2CO3 at 450â¯Â°C in air for thermal energy storage. Electrochemical measurements combined with advanced microscopy and microanalysis techniques were employed. NaClâ¯+â¯Na2CO3 was found as the most aggressive salt at 700â¯Â°C. The attack morphology on the surface was uniform corrosion with no localized degradation at 450â¯Â°C. Microscopy observations showed grain boundary oxidative attack as the primary corrosion mechanism at 700â¯Â°C with depletion of alloying elements from grain boundaries.
