Authors: KARLSSON A. , MOELLER P. J. , JOHANSEN V.
Published: May 2016

Fume gas containing 50‐500 ppm SO2, 1‐2 g/m3 of alkali‐metal chloride dust, and 8‐15% O2 can cause serious corrosion damage of iron alloys at 300‐500 °C. This behavior is explained in terms of the existence of a liquid phase in a system containing Fe2O3, alkali‐metal chloride, SO2, and O2 having a melting point as low as 310 °C. The corrosion occurs on steel regardless of whether it is alloyed with Cr and Ni.
