Difference between SSC, SCC and HIC? 1

[starrproe]

Hi All,

This question may sound a bit stupid to the experts here in this forum, but I just can't resist myself asking you guys as the issue has been bogging me for quite some time.

What is the main difference between the corosion mechanisms - Stress Corosion Cracking(SCC), Sulfice stres corrosion(SSC) and HIC(Hydrogen Induced Cracking)?
Does NACE standard address all these corrosion mechanisms?

Any ideas are welcome.

Regards,
Starrproe

The terms are defined in ISO 15156 Part 1 and repeated in ASTM G193.

If you don't have direct access to the above references just Google them on the internet. There is plenty of information in the public domain.

the main difference between the SSC / SSC and HIC is that in the Stress related mechanisms there must be an applied stress, it could be also a residual stress, while in the HIC the stress component is not present.
