Why is SS 316 resistant to Urea?
SS 316 shows excellent resistance to Urea due to its molybdenum content providing superior resistance to chlorides and corrosive chemicals compared to 304.
⚠️ When NOT to use SS 316
Avoid using Stainless Steel 316 with hydrochloric acid, hot sulfuric acid, and reducing environments. Best general-purpose stainless steel for chemical exposure.
