Hello,
I have a question about bimetallic corrosion please. If the process flange of a pressure transmitter is made of hastelloy c-276 and the 2 valve manifold for the transmitter is made of super duplex, would bimetallic corrosion occur?

Thanks
 
You are talking about galvanic corrosion, which is driven by electrochemical potential differences.
In most environments 276 and SDSS will behave similarly. If both alloys fully resist active corrosion in the working environment then there will now galvanic corrosion impact.

Thank you for the reply.
