316L stainless steel is rusting in boiling water
Hello I find you site and I think that you can answer to my problem.
I use stainless steel 316L for level indicator in a boiler.
After one month of use the stainless steel indicator inside the boiler are rusting and getting smaller. The thickens of the metal is R2mm.
Thanks for your help.

Could there be iron contamination on the surface of the indicator? Passivating it should help. Let us know if we can help.

Are you sure it is made of 316L, which should be passivated by your supplier? Otherwise, it may appear spotty rust instead of uniform rust and not reduce its dimension. All can be determined if you want to.

Have the wetted parts electropolished to increase corrosion resistance to a higher degree than passivating alone.
