Mixtures of hydrofluoric (HF) and nitric acid are the most common and are generally the most effective. Acids are available as a bath, a gel or a paste. Commercially available mixtures contain up to about 25% nitric acid and 8% hydrofluoric acid.

Type 304/L stainless is widely used in the handling and storage of nitric acid up to 60% concentration and up to the atmospheric boiling point (Figure 1 above). It has been commonly used for cooler condensers operating as hot as 200°C (390°F). The stabilized 18-8 grades, 321, and 347 are also used.Passivation of Stainless Steel Products FinishingNov 01, 1998In addition, it also describes passivation as "the chemical treatment of stainless steel with a mild oxidant, such as a nitric acid solution, for the purpose of enhancing the spontaneous formation of the protective passive film."
