Description
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.
