Electrochemical corrosion problem
Thread Content
The reactor is made of 316L material, while the agitator and internal coils are made of 321 material. The media used are sulfuric acid, nitric acid, and solvents. Is there a risk of electrochemical corrosion? If so, how can it be addressed?
Without considering electrochemical corrosion, even simple chemical corrosion is too much to handle
It depends on the concentration of the acid. From your post, it seems that there’s no major issue using this material. Corrosion is inevitable; the key question is how much corrosion is acceptable?
Since 316L is used for reaction vessels, why aren’t the internal coils and stirrers made of the same material?
This system is amazing; stainless steel simply can’t handle it.
