Corrosion Resistance and Susceptibility of type 304 Austenitic stainless Steel in Strong acids.

The resistance and susceptibility of austenitic stainless steel - Type 304 exposed to strong tetraoxosulphate (VI) and 1etraoxophosphate (V) acids contaminated with sodium chloride at umbicnt temperatures was investigated by the weight-loss method. Scanning Electron Microscope (SEM) was used to examine and characterize the test specimens' surface after tmmersion in the corrosive media. Surfacecorrosion deposit composition was analyzed with SEM paired with Energy D{spersive Spectrometer (EDS). This paper reports the • observed severe general - and pitting corrosion; and the resistance of the steel to con·osion at different concentrations of the acid chloride media
