Can nickel alloy plates resist hydrofluoric acid corrosion?

I also have a question: can titanium alloy plates resist corrosion by hydrofluoric acid? Titanium alloys are pitted by hydrofluoric acid at very low concentrations, resulting in holes the size of eggs (there are such cases)
Monel 400 alloy is relatively suitable for hydrofluoric acid
Titanium alloys are not resistant to hydrofluoric acid corrosion; consult corrosion data and material selection manuals.
PPH and HEPE plastics can be selected for storage depending on concentration and temperature
Nickel plates are suitable for strong alkaline media； Titanium plates are suitable for low-concentration chloride environments, and are particularly appropriate for media containing organic chlorides ； Neither is resistant to hydrofluoric acid corrosion
However, nickel alloys with a high nickel content, such as Inconel, can resist corrosion by hydrofluoric acid
C276 is better to use; titanium cannot resist HF corrosion
Alloys in the Incolnel series have this function
Not all nickel-based alloys can resist hydrofluoric acid corrosion well; those that perform better include Hastelloy, Monel, and nickel-based alloys such as Inconel 600! However, nickel-based alloys are relatively susceptible to corrosion by elements such as elemental sulfur
Our company, Shanghai Yongfeng International Trade Co., Ltd., is a professional supplier of imported nickel-based alloys, with a large inventory in stock. If you have any needs, please feel free to contact Xia Chengrong at 13524626523. The properties of nickel alloys also depend on temperature; MONEL400 is a good choice
We use nickel-based ones here, and the results are quite good
