“…Bromine is more oxidizing than oxygen (Lee et al, 1983), thus it raises the corrosion potential and favors pitting, crevice corrosion, and SCC. The SCC of type 316L stainless steel due to the presence of bromine species was reported in air ejector condenser systems (Black & Morris, 1981;Nordin, 1983) and venting pipes of MSF plants (Lee et al, 1983). Pitting and uniform corrosion of 316L were also reported in Br 2 solutions (Hodgkiess et al, 1985), and it was related to bromine reduction reaction, Eq.…”

“…Similar to the situation for pitting corrosion, the SCC in halides other than Cl − solutions received comparatively less attention. Some cases of SCC were reported for austenitic (Griess et al, 1985;Itzhak & Elias, 1994;Itzhak et al, 1996) and martensitic (Downs et al, 2007) stainless steels in the presence of bromides or other bromine species (Lee et al, 1983;Nordin, 1983). Similar to Cl − solutions, sensitization is not required for SCC occurrence in Br − solutions.…”

“…(1) that yields bromides. To prevent this type of failure, it was proposed to use higher alloyed stainless steel like 904L (Black & Morris, 1981;Nordin, 1983) or strict control of pH, chlorination level, and ammonia content in feedwater (Oldfield & Todd, 1981;Lee et al, 1983).…”

Fluorides, bromides, and iodides, despite being less common than chlorides, are present in various environments of industrial relevance. Stainless steels suffer pitting corrosion in solutions of all halides except fluorides, which can be understood considering that fluoride is the anion of a weak acid. The aggressiveness of the rest of the halides for pitting corrosion is on the order Cl− > Br− > I− for stainless steels with Mo content below 3 wt.%. Mo is not as effective in inhibiting Br− pitting corrosion as it is for inhibiting Cl− pitting corrosion. Most of those observations were rationalized based on the effect of anions on pit growth kinetics. Sensitized austenitic stainless steel suffers stress corrosion cracking (SCC) in solutions of all halides, albeit chlorides seem to be the most aggressive. Fluoride SCC is relevant for SCC under insulation of stainless steels, and standards and regulations developed to mitigate this problem consider this ion as aggressive as chloride. For the solubilized stainless steels, aggressiveness toward SCC is in the order Cl− > Br−. The SCC of solubilized stainless steels was not observed in solutions of F− and I−, and the possible reasons for this fact are discussed.
