For the organic strong acid sodium chloride solution of PH1-2, what materials can resist corrosion? Can titanium be used?
Thread Content
Material PH1-2 contains complex organic substances as well as sodium chloride, and has a highly acidic nature; what material can be used to resist corrosion in such conditions? Seeking advice from experts, thank you!

Impervious graphite can be used for extended periods at boiling temperature in salt acids of any concentration, sodium chloride solutions of any concentration, or mixtures of these two types of solutions, without being corroded.
Hello, the temperature is that of a room-temperature solution; however, when it evaporates, the temperature rises to between 60 and 100 degrees
The operating temperature for impermeable graphite is usually between -35 degrees and 180 degrees. Under specific conditions, it can be used at 2000 degrees without being damaged.

For ordinary sodium chloride neutral solutions, titanium materials are also recommended, as their resistance to chloride ion corrosion is relatively lower compared to 2205. How can it be determined that 2205 can be used entirely in a sodium chloride solution with strong acidic components?
Titanium cannot be used. Also, I’m not aware of the concentration of chloride ions. The material choice varies greatly depending on the concentration
Well, this pH value is too low; for titanium materials, a value around 3 is generally considered safer
Graphite materials work, and they are relatively inexpensive
Organic acids, what kind of acids are they? The temperature does not exceed 100°C; is it a storage tank or a reactor? There shouldn’t be any pressure, right! I was wondering if a polymer coating could be considered to isolate the dielectric from the substrate? If the coating is applied, there will be no problems with the carbon steel containers.
