What is material compliant with NACE requirements?I agree with SJones, one thing is a material compliant with NACE requirements (hardness, heat treatments) the other things are the NACE limits for that particular materials. You can have a 316 fully compliants with NACE but that is used above the NACE limits, example 60°C or partial pressure of H2S above 1 bar..) and so on.See all results for this question

The oldest reports about sour service steel damage more than 60 years old Many organisations (like NACE or EFC), oil- and gas companies, engineering companies are still improving regulationsnace mr0103 - [PDF Document]Oct 21, 2015 · NACE Standard MR0103-2005 Item No. 21305 . Material Requirements . Materials Resistant to Sulfide Stress Cracking in Corrosive Petroleum Refining Environments . This NACE International standard represents a consensus of those individual members who have reviewed this document, its scope, and provisions.What is the hardness of NACE?The way I see it, ASME has a maximum hardness of 17 HRC, NACE has a maximum hardness of 22 HRC. It seems like a no-brainer, but don't lose sight of the other requirements regarding annealing and cold work. Although it may appear as a redundancy, it may be safest to simply order your material c/w NACE certificates.See all results for this question
