NACE MR0175 Hardness Requirements Summary by nhirpara1 is a document available to read on EtoBox.
NACE MR 0175/ISO 15156 is a materials standard that specifies corrosion resistant alloys that can be used in oilfield equipment where hydrogen sulfide is present. It limits the maximum hardness for materials including various grades of stainless steel. A wide range of alloys are covered, including ferritic, martensitic, austenitic, duplex, and precipitation hardening grades of stainless steel with maximum hardness limits ranging from 22 to 35 on the Rockwell C scale depending on the specific alloy.
