Is the strength of SA 105 HIC different from SA 105 N?

RE: SA 105 HIC
Did you find it? Didn't think so.
HIC is a generic term used for the treatment of steel during it's manufacturing process to prevent Hydrogen Induced Cracking.
I wasn't aware of any forging companies that were doing this process.
RE: SA 105 HIC
Yes, HIC requires chemstry control for material. Does SA105 HIC still need to be normalized? Since the Carbon content is reduced or controlled to 0.23%, is its strength the same as SA105N?

RE: SA 105 HIC
If you are indeed getting HIC certified material, you should also spec out the NACE testing requirements on your order.

RE: SA 105 HIC
In addition to your topic, take note of the NACE MR0175, Clause 8 (Evaluation of carbon and low alloy steels for their resistance to HIC/SWC), this will help you understand the selection and testing requirements for the forging materials to prevent the HIC.
