What material is used for nitrate solution pumps?

What material should be used for pumps handling nitrate solutions with a specific gravity of 1.5 and a temperature of 80 degrees?

:Why doesn’t anyone recommend using fluorinated linings?
Fluorinated lining pumps will work. My family does it.
Nitrate corrosion is not very strong; cast iron with a concentration of 10% or less can withstand it. Then why are such high-grade materials recommended upstairs? Common materials such as CS, 304, 316, etc., can all withstand it
It seems that fluorinated lining pumps can be used for almost anything, except in high-temperature and organic solvent environments?
Fluorinated lining pumps really can’t withstand high temperatures; the PFA material used in China can only handle up to 150 degrees. In acidic or alkaline media, with a durable mechanical seal, its service life is excellent.
It can crystallize and form particles even when containing the element salt; dual-phase steel has good wear resistance. Personal opinion
