Naoh corrosion stainless steel
Witryna10 lut 2011 · Using austenitic stainless steels (300 series) instead can mitigate but not eliminate the risk of caustic corrosion. Experiments have shown that austenitic … Witryna9 wrz 2024 · The best materials for storing NaOH are, of course, stainless steel. However, stainless steel does corrode over time and can be impacted by a number of factors. Temperature, the concentration of the solution, and the thickness of the steel’s protective magnetite layer all play a part in the effectiveness of caustic soda storage.
