Is 22HRC the only requirement to meet NACE MR0175?


No, a maximum hardness of 22 HRC is one of the requirements for some carbon steel and low alloy steels and it is not the only requirement. In this video, Ivan Gutierrez, Managing Director of OGC Energy discusses what other requirements need to be fulfilled to meet NACE MR0175.

Carbon and low alloy steels must meet requirements of chemical composition, heat treatment, and HIC resistance to fulfil the NACE MR0175 requirements. The risk of HIC and other cracking mechanisms needs to assessed.

Stainless steels and other Corrosion Resistant Alloys (CRAs) have additional requirements. Furthermore, for each type of CRA, different applications may have different requirements, e.g. downhole components requirements may be different to valves and pipeline material.
