I design downhole tools for the petroleum industry and have a question with regard to the effect of hydrogen sulphide on low alloy steels with a hardness up to 36Rc. The normal route would be to use AISI 4140/45 with a maximum hardness of 22Rc. However, I have tools in a remote location which are AISI 4140 30-36 Rc and my customer wants to use them in an H2S environment. The exposed duration time will be relatively short (24 hours max.) and the levels of H2S fairly low (approx. 10000 ppm).
Does anyone know if there is documented information which relates to this or does anyone have experience of using these or similar steels in an H2S environment?
Thanks in advance for any help.
