pH shifts and stainless steel
pH shifts and stainless steel
(OP)
I was wondering what the effects on large pH shifts are on stainless steel. We have a process in which we switch the pH in a couple of rinse tanks from Sulphamic Acid pH 2.0 to Sodium Hydroxide pH 12.0 and 316SS Bearings being used in the process seem to be affected by it. Does anyone now what the effects are and any suggestions for a stainless grade or other material that could handle this pH shift better?

Can the bearings be Cr plated? Or since the corrosivity of the media is minimal, maybe try a harder martensitic stainless, e.g 431 or 440A.
