Corrosion behavior of AISI316L and SAF2205 stainless steels in acetic acid solution containing Br- was investigated by measuring the corrosion weight loss.Pitting characteristic was inspected by optical microscope.The corrosion rate was markedly increased with increasing temperature and Br- concentration.The pitting resistance of SAF2205 stainless steel was superior to that of AISI316L.The corrosion rate of AISI316L stainless steel rapidly decreased with increasing exposure time,while the corrosion rate of SAF2205 stainless steel slowly increased.The corrosion rate of AISI316L and SAF2205 stainless steels slightly changed after 72h.Cl- was more aggressive than Br- in 80% acetic acid solution at 80℃.Small amount of Br- had a remarkable inhibiting effect on corrosion behavior in acetic acid solution containing Cl-,whereas addition of small amount of Cl- to acetic acid solution containing Br- did not have significant harmful effects.
