Why is SS 304 rated this way to Hydrogen Fluoride?
SS 304 has limited resistance to Hydrogen Fluoride. Short-term exposure may be acceptable, but prolonged contact is not recommended.
⚠️ 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.
