Chloride Stress Corrosion Cracking w/o O2

Chloride Stress Corrosion Cracking w/o O2

Chloride Stress Corrosion Cracking w/o O2

(OP)
Can chloride stress corrosion cracking occur with stainless steels in the absence of dissolved oxygen?

-Mike

RE: Chloride Stress Corrosion Cracking w/o O2

O2 will accelerate the phenomena, there is no clear answer regarding a lower O2 threshold where SCC will not occur.

RE: Chloride Stress Corrosion Cracking w/o O2

Other oxidants such as ferric ions would not need the presence of oxygen

RE: Chloride Stress Corrosion Cracking w/o O2

With no oxygen it will slow the initiation, but even a very small amount of any oxidizer will kick the process over.
