Table A.2 of NACE MR0175 / ISO 15156, Part 3: 2016 edition (Austenitic SS’s in “sour” services)
(OP)
I’m not sure on how the table in object should be read.
Do both the 2nd and the 3rd rows refer to “Austenitic stainless steel from materials type described in A.2”?
So those materials should be used for service fluids with:
- chlorides concentrations ≤ 50 mg/l
or
- H2S partial pressures ≤ 100 kPa and temperatures ≤ +60°C.
Is this the right interpretation of the table?
(The graphical format doesn’t assist in a good understanding…)
Please see also thread338-415235: The application of austenitic stainless steels for instrument as per NACE MR 0175 (ISO-15156) about similar issues.
THANKS in advance to All,

And the remarks often do not help make things more clear.

If the item being dealt with does not satisfy the specific application description in the table title, then the default option is to use the "any equipment or component" table. Table D.1 can be used to identify which UNS number is associated with which table.
