Conflict between nickel alloy (625) in cold work preparation and nace mr 0175/ iso 15156

hi,
I want to know is there any conflict between alloy 625 (pipe) in cold work condition with nace mr 0175/ iso 15156.

There will be no conflict if the requirements of A.4 in ISO 15156-3 are met.

please help me to find the material type (4a or 4b or 4c or 4e or 4d) in table a.12 which have been specified the alloy 625(pipe which has been made with cold working) for solution annealed condition.
what requirements are there for the pipe (Inconel 625) which made with cold work.

Best Regards,

As I can read from the table A.14, the process limitations (H2S, Chloride and pH) are applicable for Alloy 625 above 149 Deg C application only. Also the Criteria is given if it is wrought or cast solid solution nickel base products,
Hardness: 40 HRC
Yield Strength: 150 ksi
Just meet these requirements. I think its enough

In your first post you said cold worked, inferring that it was to be used in the cold worked condition.
Then you said 'cold worked and annealed' which is a different animal.
If the material is annealed we don't really care what happened to it before.
