H2s and carbon steel
WebSep 15, 2016 · Embrittlement process. At room temperature, hydrogen atoms can be absorbed by carbon steel alloys. The absorbed hydrogen may be present either as atomic or molecular form. Given enough time, the hydrogen diffuses to the metal grain boundaries and forms bubbles at the metal grain boundaries. These bubbles exert pressure on the … WebProcess fluids in sour service contain hydrogen sulfide (H 2 S) which is known to be corrosive, flammable, and toxic. This corrosivity can push alloys to their limits and contribute to sulfide stress cracking (SSC) in higher-strength carbon steel and low-alloy steel. SSC can lead to material embrittlement and sudden failure of normally ductile ...
