What is NACE treatment? What specific requirements does MR1013 refer to?

Which expert can provide a detailed explanation!
NACE refers to the National Association of Corrosion Engineers in the United States. What you are referring to is likely NACE MR 0103, which deals with the selection of materials resistant to sulfide stress cracking in corrosive environments associated with oil refining; you can download this standard to view the specific requirements
NACE covers not only the selection of materials but also surface treatment. Nowadays, some design institutes explicitly require NACE treatment for certain parameters; so the question is, what exactly is the required treatment? For example, if a 304 flange requires NACE treatment per the customer’s request, what should I do? Could someone with expertise give me some advice?
NACE treatment must refer to heat treatment, right?
Personally, I feel that this standard is merely a criterion for material selection, imposing certain requirements on the heat treatment state and welding of the materials. It is not the standard for material processing. If it is 304, it belongs to austenitic stainless steel, falls within the range for empirical selection, and can be used directly under certain heat treatment conditions.
