Hydrogen stress cracking is the same mechanism that is responsible for sulfide stress corrosion cracking in wet H₂S environments except that HF acid is generating the __________.

Question

Quizplus · Accepted Answer

Hydrogen stress cracking occurs when atomic hydrogen is present in a metal and becomes absorbed into the metal's microstructure. This can occur during the corrosion process, specifically in the presence of hydrogen-containing fluids such as water or acids like hydrofluoric acid (HF). Once absorbed, the hydrogen atoms can cause the metal to become brittle and eventually crack, leading to failure. Therefore, the correct answer is C, hydrogen is generating the stress cracking, not sulfide or caustic.
