QUESTION: Typically, when an indentation fails the micro hardness test several additional indentations are made and measured in the same area as the suspect indentation on the same weld test coupon. The results are then averaged. If the additional indentations average is acceptable, the survey is considered acceptable. This is in line with the NACE MR0175 Part 2 Section 7.3 "Hardness" paragraph 7.3.2 "Parent Materials" which allows additional hardness readings in the adjacent areas of a failed hardness reading. Logically, the same testing methodology would apply to welds, even though it is not specifically stated in the standard and subsequent paragraphs of Part 2. I would like to clarify if the above is acceptable with regards to Vickers HV 10 micro hardness testing / re-testing requirements for welds while conforming to NACE MR0175 Section 7.3.3 Welds. ANSWER: Maximum acceptable hardness values for carbon steel, carbon-manganese steel and low-alloy steel welds are...

Question: In NACE MR0175/ISO 15156 -3, Table A.22 lists the “Environmental and materials limits for martensitic stainless steels used as compressor components.” The maximum partial pressure requirement for H2S directs you to see Remarks, and the Remarks state “Any combination of temperature, partial pressure of H2S, chloride concentration and in situ pH occurring in production environments are acceptable.” Does this remark indicate that conformance to the NACE MR0175/ISO 15156 is required for any amount of H2S? I am looking for clarification as to what “acceptable conditions” is referring to. As a centrifugal compressor manufacturer, we often build compressors for process gases which are a hydrocarbon mix containing a few parts per million or trace amounts of H2S. Answer Conformance to the Standard is required for any trace amount of H2S. In the case of Table A.22 the listed martensitic stainless steels can be used in any production environment provided they are in confor...
