This post was last edited by Sammy_Wang on 2016-2-23 at 13:46. Last year, I received an order for a valve made of PFA with fluorine lining and a stainless steel 304 body. The medium being handled is hydrofluoric acid; there’s no pressure or temperature involved. Which material would be the most suitable choice?

Of course, using PFA material lined is better; 304 steel is not suitable for handling hydrofluoric acid!

I just know that Hastelloy is really amazing

It’s awesome, no doubt, but it has to be suitable as well
