Abstract
Austenitic and ferritic steels were exposed in the superheater
area of a straw-fired CHP plant. The specimens were exposed for
1400 hours at 450-600°C. The rate of corrosion was assessed based
on unattacked metal remaining. The corrosion products and course
of corrosion for the various steel types were investigated using
light optical and scanning electron microscopy. The ferritic
steels suffered from corrosion mainly via material loss. The
austenitic steels suffered from predominantly selective corrosion
resulting in chromium depletion from the alloy. A clear trend was
observed that selective corrosion increased with increasing
chromium content of the alloy.
