Can 316L resist corrosion by sulfuric acid and phosphoric acid?
Thread Content
316L is also used for stirrer tank coils. Condition 1: Contains 1% sulfuric acid solution and 2-3% phosphoric acid solution, with a solid content of 20% ； Condition 2: Contains 10-20% phosphoric acid, with a solid content of 20%. I would like to ask about the corrosion resistance of 316L under these two operating conditions
316l is a type of stainless steel. 316L is a grade of stainless steel material. As a type of stainless steel, it possesses excellent corrosion resistance due to the addition of Mo element during its production. By welding it after cutting it into sections and then performing annealing treatment, the best level of corrosion resistance can be achieved. Its corrosion resistance allows it to be safely used in environments with acidic ions
Could I help you provide a polyaniline hanging strip to try it out?
Used as a stirrer tank coil; the temperature is not clearly specified. It can be used in liquids containing sulfuric acid at temperatures not exceeding 50 degrees. It can be used in liquid phosphoric acid without any problem.
A higher temperature is not recommended in Condition 1: a solution containing 1% sulfuric acid and 2-3% phosphoric acid with a solid content of 20%.
All of your requirements seem unsuitable to me.
--The specific concentration and temperature data regarding corrosion resistance to sulfuric acid and phosphoric acid are shown in a diagram that is quite large; you can send a private message for those details
