RE: HIC severity level
A full HIC/blistering control program includes baseline PAUT of the steel, so that damage progression can be assessed.

B) Is it Wet
C)Is it tested for HIC
D) Impurities
If its not rated to TMO-284/NACE rated, has impurities is wet and is in a sour service you have a problem.

RE: HIC severity level
Hi Nick, service is sour and wet. No HIc test. I dont have idea about impurities.
Can you explain me about TMO rate?
RE: HIC severity level
Hi,
You can find a copy of TMO-284 here

Essentially inclusions/impurities within your material act as a nucleation sites for Hydrogen atoms, this leads to HIC.
It is particularly important for flat rolled pipework which is more susceptible than seamless.
I would suggest looking at ISO 15156/ MR0175 to find out what your threats are and whether you need to carry out inspection ie Phased array
Best regards,
Nick
RE: HIC severity level
With regard to the original question, it may be that the OP is seeking the HIC equivalent of the SSC Region diagram in part 2 which does not yet exist.
