    Lower limit of H2S partial pressure in NACE MR0175/ISO 15156 for CRA material

    Hi Sjones, Thank you for the link. I will look into it in detail. I was under the idea that the FCC structure of austenitic stainless steel could perhaps give it a better resistance to cracking in terms of hydrogen diffusion when compared to BCC structure. As such a lower limit of H2S...

    Lower limit of H2S partial pressure in NACE MR0175/ISO 15156 for CRA material

    Hello, Good day to all, I would like to know, what is the Lower limit of H2S partial pressure in NACE MR0175/ISO 15156 for CRA material? It is stated that for carbon and low alloy steel, SSC is not expected unless the H2S partial pressure exceeds 0.3 kPa (sour service) However, for CRA...
