NACE MR0175/ISO 15156 SSC for CS weldments
(OP)
Hello Mates,
I have seen and it is quite crystal clear that SSC may be applicable to Materials and well described in NACE/ISO. Any idea under which circumstances it may required for weldments and forced us to do for PQR in Sour Services. Any reference to NACE Clause is appreciated.
Thanks

Thanks for your reply. Actually I have to rephrase my question.
The SSC test may be applicable to CS and low alloy base metals. The SSC test is not applicable to CS and LAS weldments as long as they met the hardness requirements as per clauses 7.3.1 and 3. Is that correct understanding?
Thanks

Under which circumstances we may or dictate to ask for SSC for weldments based on your experiences.
Thanks

Your question boils down to: can you trust ISO 15156 as it stands, or are you so uncomfortable with it that you require some alternative form of material performance verification? We can't advise on how to feel about it. It's a philosophical question about how much compliance is enough.

Chemistry is fairly straight forward, but hardness testing not so much. How many tests, done where,and by what method. If you are sticking with chem and hardness (which has been shown to work) then you might want a little more support data supplied.
