Abstract
The effects of dissolved ozone and peracetic acid on the corrosion behavior of several stainless steels were tested in laboratory by electrochemical e xperiments and immersion tests. In chloride-free solutions, the corrosion r ates of highly alloyed stainless steels are slightly higher than those of l ess alloyed steels. Both intergranular corrosion and pitting occur on the s tainless steels. Critical temperatures and chloride concentrations of pitti ng and crevice corrosion in ozonated and peracetic solutions have also been determined.
