In the past, generally use strong corrosive hydrofluoric acid and nitric acid removal method.309/309s Stainless Steel | AK Steel309/309S STAINLESS STEEL Properties CORROSION RESISTANCE Types 309 and 309S provide excellent general corrosion resistance. They are more resistant to marine atmospheres than Type 304. They exhibit high resistance to sulfite liquors and are useful for handling nitric acid, nitric-sulfuric acid mixtures, and acetic, citric, and lactic acids.Nitric Acid Storage Tanks On | nitric acid tank | General 304 stainless steel nitric acidNitric Acid Storage Tanks; Nitric Acid Storage Tanks.
