Why is SS 304 resistant to Cyclohexane?
SS 304 shows excellent resistance to Cyclohexane due to its chromium content (18%) forming a passive oxide layer resistant to many corrosive environments.
⚠️ 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.
