Corrosion of stainless steel 316Ti tank for the transport 12-15% of hypochlorite solution
Abstract
The corrosion of the transport tank materials made of stainless steel 316Ti is investigated in a solution containing 12-15% of the commercial sodium hypochlorite solution. Using the electrochemical techniques, weight loss measurements, and optical microscope, it is shown that corrosion occurs due to the metastable pitting. It is proposed that formed metal oxides corrosion product could catalyzed chemical decomposition of hypochlorite solution to oxygen, which provokes the positive shift of the corrosion potentials into the region of metastable pitting.
