Chloride Stress Corrosion Cracking
Chloride Stress Corrosion Cracking
(OP)
Refer to ASM Handbook Vol. 11, chloride plus moisture contribute to stress-corrosion cracking (SCC) of high- strength steels.
Refer to API RP 571, carbon steels and low alloy steels are not susceptible to chloride stress corrosion cracking.
Please advise me about the discrepancy in these documents.

RE: Chloride Stress Corrosion Cracking
This topic gets complex rather quickly. Look at the FAQ's under the Welding, Bonding & Fastener Engineering Forum for more information. If that doesn't answer your question or need more information please post.
RE: Chloride Stress Corrosion Cracking
Thanks for the comment. I think you intend to specify 160 ksi instead of 160,000 ksi.
I cannot find such FAQ's under the Welding, Bonding & Fastener Engineering Forum. Could you please show me the link?
RE: Chloride Stress Corrosion Cracking
By the way if you find the 160,000 ksi steel let me know.
The 160 ksi is still a good number.
Check the references in FAQ725-600. I'll have to check the forum where I thought It was mentioned.
Sorry about that.
RE: Chloride Stress Corrosion Cracking
From ASM Handbook Vol.11, steels with yield strengths of approximately 1379 MPa (200 ksi) or higher are especially susceptible to SCC. However, SCC failures of mild steel and low-strength alloy steels are also quite common.
I would like to ask for the comment especially for chloride SCC in high strength steel. Please share your experience.
RE: Chloride Stress Corrosion Cracking
Thread725-95071 is quite informative.
