ASTM A516 grade 65 steel plate is used throughout the oil, gas and petrochemical industry. A516 grade 65 steel plate is also found in sour service and wet H2S applications, where the steel is HIC tested. The maximum thickness of ASTM A516 grade 65 steel plate is limited only by the capacity of the composition to meet the specified mechanical property requirements.
