The Effect of Lead on Dealloying and Stress Corrosion Cracking (SCC) of Ni-Cr-Fe Alloys in Boiling Caustic Environments
304L stainless steel (SS) samples were exposed to a highly caustic 50 wt.% NaOH environment at or near the boiling temperature (135-140 °C) in reducing conditions to study dealloying. Flat samples were used for electrochemical measurements, and SS 316L was used in some tests to evaluate the effect …
