NACE: MR0175 and MR0103


What is NACE?
NACE International, formerly known as National Association of Corrosion Engineers, is a world wide corrosion soci-ety. NACE International provides and publishes standards such as the MR0175 and the MR0103. In these standards, NACE International provides guidance on which corrosion resistant alloys and materials should be used for preventing sulfide stress cracking. These guidelines are determined from the collection of laboratory experimental data and field experience related to cracking resistance of metallic materials in a hydrogen sulfide (H2S) containing environment. In the NACE International standards, a H2S containing environment may also be recognized as a “sour gas environment.”



NACE MR0175 and MR0103 Standards

The NACE MR0175 standard, also known as ISO15156 (International Standard), was developed for the prevention of sulfide stress cracking due to H2S in oil and gas production systems. Historically, for the refining process, the MR0175 standard was used as a guideline for choosing suitable materials. However, the refining process environment is out-side of the scope of the MR0175 standard. The NACE MR0103 standard was developed to be a refinery-specific sour service materials standard. Like the MR0175 standard, the MR0103 standard provides recommendations on which alloys and materials to use to prevent sulfide stress cracking in an H2S containing environment.
