    Sulfinert Coating vs passivation layer of Nickel alloys

    For equipment that is used to analyse ppm of sulfur-components we use Sulfinert(R)-layer of stainless steel. Now I got a question if we can use a Nickel alloy 625 (UNS N06625) that is not Sulfinert(R) instead. Alloy625 is very good in H2S environment, but applying Sulfinert(R) coating is...

    AISI316 pipe carrying CO2 at temp above 60deg C

    I want to use a test flow loop of Aisi316 stainless steel, to performe fluid test of a hydrocarbon gas with high CO2 content. The H2S content is very low and there is no water in fluid and no chlorides (the customer hope there is no chlorides present). The customer now tell us that they have...

    Aisi4130 & Aisi4140 strength @ 150deg C

    I am looking for strength at temperature for the Chromium-Molybdenium steels AISI4130 & AISI4140. I can find alot of info about strength for stainless steels at temperature, but when I am going to verify the strength of equipment at temperatures up to 150deg C for carbon steel alloys it is not...
