Corrosion Resistance to 316 ss


I would like to know if the stainless steel grade 316 have resistance to water with pH 4.5-5.0.

Thank you.

316 stainless steel should be resistant to this pH with no problem. However, it depends on what chemicals you have in the tank. If chlorine is present, for instance, it could be a problem. If the pH is caused by organic materials it should work fine.

There are consultants available in the industry who could give you a more concrete answer if they know the exact chemistry.

Regardless of the chemistry, it is critical to passivate the surface before exposing it to the lower pH to give optimum resistance.
