For a specific material, High-Temperature Hydrogen Attack (HTHA) is dependent on temperature, hydrogen partial pressure, time, and alloy composition. The alloy composition, particularly the content of chromium (Cr) and molybdenum (Mo), plays a significant role in resistance to HTHA.
High-Temperature Hydrogen Attack Resistance to HTHA increases with an increase in the alloy content, primarily the Cr and Mo content, of a steel. For a specific material, HTHA is dependent on temperature, hydrogen partial pressure, time, and stress level.
