What material is suitable for the floating roof panels in naphtha tanks? Which one is more reliable: LF4, 5083, or 18-8? And state the basis.

A little more of LF4 is needed; our plant also uses it in the reforming feed tanks, and sometimes we find that the aluminum plates have been corroded

I hope someone can answer. Based on atmospheric and vacuum naphtha. LF4 won’t work – it suffers from corrosion; its lifespan is 5–6 years. 0Cr13 also won’t work; its lifespan is 2–3 years. I’m not sure about 18-8; I’m worried about chloride ions. What about 5083? What is it?
