Warning
Corrosion resistance to nitric acid drops off rapidly at concentrations above 65% – consider using aluminum or a high-silicon cast iron for such applications.
Note:
Best resistance to nitric acid of any stainless steel – but still may not be good enough in highly concentrated (>65%) acid. 304L Special (with extremely low carbon and low silicon, phosphorus and sulfur contents) is an improved version of this steel.
