lime calcium chloride blend

[siretb]

Hi
Solids, some humidity present in atmosphere .? about 15% huimidy volume% in above atmosphere)

Would a blend of clacium chloride (CaCl2,6H2O) 70% wt and lime (Ca(OH)2 30% corrode carbon steel at 70°C

If the level of calcium chloride is 70 %, definitely CS is not suitable while lime water (Calcium hydroxide) is not corrosive. Refer to the below.

If you are looking for the data with calcium chloride with lime (7:3), you need specific test on your own.

Although I do not know the details but you may need to consider non-metallic coating.

Dear siretb,

CS would develop weld cracks around 65⁰C in the said service.

Thank you all.
If I understand correctly, the alkalinity of the lime will not mitigate the corrosive potential of calcium chloride

Dear siretb,

Lime alone is capable of producing those weld cracks in CS.

hi,
is that a solid powder or a water solution? If a solution, you haven't specified the concentrations.
