Compatibility Rating
At 20°C (68°F)
Fair
Limited resistance - short-term exposure only
At 50°C (122°F)
Poor
Not recommended - significant degradation expected
Why is SS 304 rated this way to Chlorine Dioxide?
SS 304 has limited resistance to Chlorine Dioxide. 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.
