What is difference between Incoalloy 825 & Inconel 625
(OP)
Dear Friends.
We have a test separator for offshore oil platform. As per drawing the vassel has to be overlaid with Incolloy 825 but the vendor has done with Inconel 625. The vendor is now arguing that the Inconel 625 is having higher Nickel and Chromium content and has better corrosion resistance properties.
Please let me know the difference between these two and which one is suprior?
Thanks & regards,
Sunny Sapar

Most would argue any Ferrari is 'better' than a Dacia Duster, but Id rather take the later when going off-road.

625 is a Ni based alloy with much better high temp properties than corrosion resistance. Just based on raw material values 625 is 3-4 times the price of 825.
