What makes a Carbon Steel HIC Resistant?
(OP)
Could anyone explain what makes a Carbon Steel HIC Resistant?
I am involved in a relatively small fabrication in the UK, where the materials of construction are specified as ASTM A333, A350 LF2, P355, A420 WPL6 but the materials are also specified to be "HIC resistant Carbon Steel".
What steps do we need to take to ensure this requirement is met?
Thanks in advance

Without getting into too much detail, the following publication by Bethlehem Lukens describes their HIC-Tested pressure vessel plate steels.

Thanks for your concurrence. Just to clarify, if we maintain two significant digits, then < 23 HRC IS 22 HRC max. This number is a guideline, but low sulfur, low segregation, and low grain size all allow higher hardness material to be used.
