Nitric acid storage tank material selection
Thread Content
What material should be used for the 68% concentrated nitric acid storage tank? What material should be used for 20% dilute nitric acid? What kind of storage tank material is needed to dilute 68% concentrated acid to 20% (considering the heat released by dilution)?
What I use here is fiberglass, which is corrosion-resistant{:9001:}
Check the corrosion curve. If the temperature is below 60℃, choose 321.
Also provide one for comparison. It’s not bad to give.

May I ask which book the two screenshots above are from? Thanks
Try not to use fiberglass for pure nitric acid, and 316L is recommended. It doesn’t matter if the concentration is below 80%, there are no specific requirements.
