What is a NACE MR0175 material?

What Is a Nace Material?

A NACE material is a type of metallic material that meets the requirements of NACE MR0175, a document published by the National Association of Corrosion Engineers (NACE) that provides guidelines for metallic materials exposed to H₂S in oil and gas production environments.

What Is Nace Piping?

NACE piping refers to piping made from NACE-compliant materials that meet the requirements of NACE MR0175. This type of piping is used in H₂S environments within the limits set by the standard.

What Is a Nace MR0175 Compliant Steel?

A NACE MR0175 compliant steel is a type of steel that meets all the requirements of NACE MR0175, including metallurgical requirements such as chemistry, hardness, heat treatment, and HIC resistance, as well as environmental limits such as the amount of H₂S expressed as partial pressure, maximum chloride content, pH range, and more.

Where Is the Definitive List of Nace MR0175 Compliant Materials?

There is no official list of NACE MR0175 approved materials. Our team can provide information on common oil and gas materials that comply with NACE MR0175 as well as answer questions related to NACE compliance and the NACE MR0175 requirements for a specific material.

It is important to note that hardness below 22HRC is required for some materials, but it is not the only NACE MR0175 requirement. Our team can also provide guidance on how to specify “NACE material” and whether HIC is required for a specific application.
