Selection of stainless steels for handling sulphuric acid ...

Aeration or the presence of oxidising 'agents' in sulphuric acid contributes to the corrosion resistance of stainless steels. Stainless Steels have lower resistance to de-aerated sulphuric acid. Reducible ions such as Fe3+, Cu2+, Sn4+ are effectively oxidising agents and can reduce corrosion if present in the acid.
