Reza Jafari

Hi,

Fe-based material with high content of Cr (>20%) may withstand against corrosion attacks in such environments. Ni-based could provide higher resistance, but they are generally more expensive and hard to shape.

Good luck

Nuha Hadi Jasim Al Hasan

One type of Ni alloys have high corrosion resistant, see this figuer attachment for some materials

Milad Vahman

Dear Reza and Nuha,

thanks for your answers.
