The following steels have been chosen for this work: API 5AC L80, AISI 4137H, AISI 420 - API 5AC C90, 22Cr-5. 5Ni-3Mo, 27Cr-31Ni-3. 5Mo. The tests have been performed both in NACE solution, both in modified NACE solution (in which a 90% CO//2 plus 10% H//2S gas was bubbling). Smooth and precracked specimens have been used. The impossibility of using carbon or low alloy steels at high strength levels when relevant H//2S contents are present has been confirmed.

Abstract
The following steels have been chosen for this work: API 5AC L80, AISI 4137H, AISI 420 - API 5AC C90, 22Cr-5. 5Ni-3Mo, 27Cr-31Ni-3. 5Mo. The tests have been performed both in NACE solution, both in modified NACE solution (in which a 90% CO//2 plus 10% H//2S gas was bubbling). Smooth and precracked specimens have been used. The impossibility of using carbon or low alloy steels at high strength levels when relevant H//2S contents are present has been confirmed.File allegato/i alla scheda:
