NACE MR0175 umbrella covers HIC for plate material
(OP)
I have come again to that fork road where my Engineer mentions in Plate Material Spec "+NACE MR0175" when we expect the plate vendor to quote for sour service, i.e. HIC resistant.
But the vendor says he quoted with NACE but without HIC? Scope of NACE MR0175 states it “…addresses all mechanisms of cracking that can be caused by H2S, including…. Stress-oriented hydrogen-induced cracking,…”
Has anyone else faced similar problem time and again? Are we missing anything or the vendor is fooling?
Please share your experience and knowledge on this for enlightenment.

It's been a while since I've used it, but it does have various exemptions, options, and assumes that both purchaser and seller are reading and coordinating the requirements.

Also, refer to the exemptions in Table 1, which may entirely exempt the item in question from the requirements of MR0175.
