Selection of materials for storing phosphoric acid
Thread Content
75% phosphoric acid; currently 316L is being used. Is there any material that is more resistant to phosphoric acid corrosion at 150 degrees? Please ask an expert for help!

Concentrated phosphoric acid at 150°C requires PFA coating, which is quite costly
Yes, but it depends on the impurities in your phosphoric acid – is it pure phosphoric acid or does it contain fluorine, in which case is it wet-process phosphoric acid?
It can be lined with PTFE or coated with PFA; I’m not sure if the original poster has any other requirements, or whether it refers to equipment or fittings. I hope to be able to provide further answers to the original poster!
