Questions about Hastelloy

Thread Content

I have a system here that contains chlorine, hydrogen chloride, and chlorides, and I want to install an antistatic device. I haven’t been able to find a suitable material for this purpose; I was wondering whether Hastelloy could be used. Does Hastelloy react with chlorine?

According to the material selection table, Hastelloy C should work (it’s generally not listed among the suitable materials), but there should be no phosphoric acid vapor in the system

Thank you, guys upstairs. I’ll give it a try here; this system is quite complex, so I’ll start by doing some tests with materials first

Hehe, using Hastelloy is a bit of a waste, isn’t it?
