AISI2205
(OP)
Hi,
I need some help from some expert.
We have made the part in the attached picture with AISI 2205.
Is it possible that get rusted in that way?
The machine as travelend by ship and it will be installed in
a port.
Thanks

Yes, the pin is in contact with painted steel. I tought the paint will act as separator and prevent galvanic phenomena.
The weather at the port where the machine is installed it might experience very hot and humid environment (tropical climate).

It is a machined part. No welding involved. Was made from a rod of diam. 50 amd machined down to 35mm and 48mm.

My guess is that there is massive surface iron contamination that triggered the rusting.
The part should have been passivated in nitric acid after all machining.
Oh, by the way did the starting material have good corrosion resistance? Was it tested to A923, if not then the starting bar may not have had the optimal microstructure.

Are you saying that if I machine AISI 2205 I will lose the corrosion resistence properties?
Thanks
RE: AISI2205
After all machining, cutting, forming, grinding/polishing operations all SS should be passivated if you want to avoid surface corrosion.
But I will echo Stan's comment; are you positive that this is 2205?

Sice we can't take any risk, we will replace them and get back the old ones. Once they are back we will send for analysis and I will let you know.
Thanks
Bye
