Stress corrosion cracking issue caused by caesium hydroxide
Stress corrosion cracking issue caused by caesium hydroxide
(OP)
Hi guys
I am looking for information on SCC by caesium hydroxide at crica 300C. Does anyone know material(s) suitable for this type application?

are there any oxidizing ions? (O, NO3–, Cr2O7–2, MnO4–, Fe+3, Cu+2)
Without these then a high alloy stainless (6%Mo) should be fine.
With them you need some special help.

Thanks for your information
There will be some methanol and demin water.
The proposed material of construction is either 304 or 316. These materials will seeing temperature as high as 300C but for no more than 72hrs (regeneratio process.
Where can I find corrosion rate information for short exposure time?
Any thoughts?

Do you know dissociation coef and resulting pH for this system?
h
This is a good one.
Will the results be similar to NaOH?
If so then a 300 SS may not handle 300C if the pH is very high.
