What are the NACE MR0175 marking requirements?

NACE MR0175 is an international standard that provides the requirements for metallic materials exposed to H2S in oil and gas production environments.

NACE MR0175 is identical to ISO 15156. ANSI / NACE MR0175 / ISO 15156 lists the requirements for carbon steels, low alloys and corrosion resistant alloy exposed to H2S in oil and gas exploration and production environments.

NACE Mr0175 in Part 2 Clause 9 requires compliant materials to be traceable, preferably by marking. It is important that any identification stamping is low-stress type (e.g. dot- vibratory and round V). Marking on high stress areas should be avoided. For carbon and low alloy steel, NACE MR0175 Part 2 Annex E (informative) provides examples of designations that may be used to identify materials. For CRAs you can find examples of designations for marking in NACE MR0175 Part 3 Annex C

Our team can help you define suitable marking and identification methods for raw material and equipment in compliance with NACE MR0175.
