Chromic and arsenic acid

[Alwynb]

Hi there,
I am looking for a source of metal material recommendations for a tank to be filled with Chromic and Arsenic acid with water. A pointer in the right direction would be appreciated.
Thanks

What temperature and what concentrations for the acids?

Thanks for the reply. The temperature is 40°C max and 33% of each acid and then 33% water.
