Why is SS 304 rated this way to Fluorine?
SS 304 is not recommended for use with Fluorine. Significant degradation or failure is expected.
⚠️ When NOT to use SS 304
Avoid using Stainless Steel 304 with chloride-rich environments (seawater, HCl) which cause pitting corrosion. Use 316 grade for chloride exposure.
