Nickel alloys for CO2 corrosion
Nickel alloys for CO2 corrosion
(OP)
I can't find any information on the suitability of nickel alloys (Inconel, Incoloy, Hastelloy) in CO2 corrosion. Is this because this combination is a big no-no, or is it because people usually do not use this combination?
We have wet CO2, wet H2S and chlorides in the water so I have ruled out austenitic stainless steels and 410SS.

Nickel alloys are resistant to CO2 "sweet" corrosion. Usually in the Oil & Gas the alloys used are the Alloy 825 or Alloy 625. If you have also H2S then you have to follow the requirements of NACE MR0175 / ISO 15156 that gave application limits for CRA (corrosion resistant alloys) in terms of Chlorides, temperature partial pressure of H2S and presence of elemental sulfur.
