Comparative assessment of the pitting corrosion resistance and passivation behaviour of 439L ferritic and 904L austenitic stainless steels for application in extreme process environments.
Potentiodynamic polarization studies of the passivation behaviour and pitting corrosion resistance of 439L ferritic (ST439L) and 904 austenitic (ST904L) stainless steels in 3.5 M H2SO4 and neutral chloride solution at specific chloride concentrations were performed. Results showed ST439L to be relatively more resistant to general corrosion in H2SO4 solution at 1–5% NaCl (wt%) concentration...
