Corrosion
Corrosion
(OP)
Hi! I'm new to the forum and I have a question for you guys. I encountered corrosion in a metal that I'm working with. I have attached three different pictures of the corroded piece. Does anyone know what type of corrosion this is? And if so, how did you determine that?





RE: Corrosion
What "metal" corroded?
Under what conditions did it corrode?
How long was the metal exposed to those conditions?
(Pressure, chemicals, temperatures, longevity/continuous/intermittent/spray/liquid/solid all matter.)
Have you built with this "metal" before, and if so, what changed in this installation?

The piece that you are looking at is a pivot bolt of the valve disk . The third picture is a cross section of part of the corrosion. It wasn't supposed to be plated in any type of material, but it is becoming obvious that it was not the anticipated material in the least bit. Nickel plating would make sense with the composition reading. And yes, that is an O-ring.
