The short answer is NO. See the table below for more information on selection of materials used for Sour Service in the oil/gas production and processing facilities in order to mitigate hydrogen damage, such as:

  • Sulfide stress cracking (SSC)
  • Hydrogen induced cracking (HIC)
  • Stress-oriented, hydrogen induced cracking (SOHIC)

Nickel-carbon-low-alloy steels and weld metals containing more than 1.0% nickels (e.g. ASTM A333 Gr 8 with 9% Ni) should not be used in sour service. However, if low temperature materials are required, such steels and weld metals could be considered, provided the formation of liquid water is prevented at all times.
