Corrosion-resistant materials

For heat exchangers using saturated sodium chloride brine at temperatures of 70–90 degrees, with fluoride ion concentrations of 200ppm–500ppm, which steel grade offers the best performance?
It is possible to ignore the use of graphite or silicon carbide just now. The pipes are fitted with prefabricated enamel or PTFE linings.
Could we consider not using steel? Use graphite or silicon carbide. The pipes are fitted with prefabricated enamel or PTFE linings. I made a typing error just now; sending it again. For this, you can specifically contact the equipment manufacturer and ask whether their equipment can withstand it Because they have a lot of contact; if they say it’s okay but you fail to do it later, they are also responsible, so they don’t dare to speak carelessly.
Fluoride ions are present; enamel cannot be used

Although you are an expert in graphite materials, you can’t just recommend graphite heat exchangers as soon as you’re in a new environment, right? :lol;P
