Oxidation behaviour of 18/8 Cr-Ni austenitic steel in presence of Na2SO4 and NiSO4 at 650 to 1000°C

Abstract

Iron based alloys containing chromium as a major constituent with nickel additions are the most prominent materials in coal fired generating units and petroleum refinery plants. The corrosion of these alloys under service conditions is not uncommon due to deposition of molten salt(s) or ash and/or the attck of gaseous species such as O2, CO2, CO, SO2, H2S etc.
