The technological importance of the high temperature corrosion behaviour of metals in gases with a low oxygen potential and containing other oxidants is outlined. This indicates the wide interest in the role of sulphur and also chlorine compounds, their aggressiveness being such in low oxygen potentials that serious corrosion rates can occur even below 400°C. The scientific basis of our understanding of corrosion in such atmospheres is discussed, and applied to the case of corrosion in sub‐stoichiometric combustion products in pulverized coal boilers.
