New insights into the hardening and pitting corrosion mechanisms of thermally aged duplex stainless steel at 475 °C: A comparative study between 2205 and 2101 steels

R. Silva et al.

Summary: The study investigated the relationship between spinodal decomposition and the formation of Ni-rich clusters and G-phase in ferrite on the hardening and pitting corrosion of two thermally aged DSSs at 475 degrees C. It was found that for 2205 DSS, pitting corrosion behavior is influenced by G-phase precipitates, while for 2101 DSS, pitting corrosion resistance is mainly affected by the formation of Cr-richer nitrides.

A comparative study on the critical pitting criteria of a super ferritic stainless steel at different temperatures in chloride or bromide solution

Longlin Lei et al.

Summary: The critical pitting criteria of S44660 in chloride or bromide solution were investigated. The study found that the more aggressive Cl- does not necessarily lead to lower Eb values in all temperature ranges. The Eb-T curves revealed that the pitting behavior can be divided into transpassivation, transition, and pitting regions with temperature. Further investigations showed that the wider transition region in bromide solution is due to the weakened repassivation ability caused by the interaction between Br- and Mo, indicating that pitting is more likely to occur at lower temperatures in bromide solution.

Studies on the degree of sensitization of hyper-duplex stainless steel 2707 at 900°C using a modified DL-EPR test

Li Sun et al.

Summary: Thermal aging of hyper-duplex stainless steel (HDSS) 2707 at 900 degrees C for up to 26 hours has been found to affect the degree of sensitization, which initially increases rapidly before reaching a peak at 10 hours due to self-healing mechanisms involving Cr and Mo diffusion.
