Resistance of Stainless Alloys to Dilute Sulfuric Acid
Mar 13 2011 · The character of sulfuric acid undergoes a remarkable change as its concentration changes. In the dilute (<10 ) through mid-range (30-60 ) concentrations its redox potential is reducing Figure 1 . These reducing potentials in a strongly acidic environment are extremely corrosive to common steels and challenge many stainless steels One source
