Notable Finding

316 stainless steel shows a consistent chloride/halide vulnerability across this family — rated Fair or Corroded against most chloride and fluoride salts regardless of concentration, while performing well against nitrate salts. This pattern independently recurs across multiple vendor material-selection guides in LibertyCES's files, not just this chart.

FAQ

Frequently Asked Questions

What materials are compatible with salts / brines?

It depends on the specific chemical, concentration, and temperature — this page carries 114 real rated rows across 66 distinct media in this family, rating PVC, PP, PVDF, PFA, PTFE, and 316 stainless steel individually. There is no single answer for the whole family.

How current is this data?

Sourced from Flowline chemical compatibility chart, 551 real media rows. Confirm current specifications with the manufacturer before final specification — chemical formulations and vendor ratings can change.

What if my exact chemical or concentration isn't listed?

Send LibertyCES the exact chemical, concentration, and operating temperature — James can confirm material compatibility even where this reference table doesn't have an exact matching row.
