Selection of stainless steels for handling sulphuric acid …

WebStainless Steels have lower resistance to de-aerated sulphuric acid. Reducible ions such as Fe 3+, Cu 2+, Sn 4+ are effectively oxidising agents and can reduce corrosion if present in the acid. Similarly oxidising agents like chromic or nitric acid reduce corrosion rates, if present in the sulphuric acid. WebMeanwhile, the corrosion rates for stainless steel (Table 7) and copper (Table 8) vary from 1.59 9 10 -2 mm/year to 8.60 9 10 -2 mm/year and 1.06 9 10 -2 mm/year to 7.97 9 10 -2 mm/year, respec ...
