Reference Recommendations for the Corrosion Resistance of Stainless Steel Pumps to Acids, Magnesium, Calcium, Barium, Ammonium, Potassium, Nickel, Sodium, Zinc, Iron, Copper, Aluminum, and Hydrogen

304/316L stainless steel is suitable for nitric acid, weak acids, and environments containing magnesium, calcium, barium, ammonium, potassium, nickel, sodium, zinc, iron, copper, and aluminum ions. For sulfuric acid and hydrochloric acid, fluoroplastic-lined pumps or plastic pumps are recommended. Hydrogen-containing environments require special treatment.
