Why is SS 316 resistant to Ammonium Hydroxide?
SS 316 shows excellent resistance to Ammonium Hydroxide 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.
