“…I n complex industrial environments which contain more than one oxidizing species, the protective character of the chromium oxide film may be compromised, and corrosion may occur at a higher rate than in only oxygen [3]. Chlorine is present in some high temperature environments produced during incineration of municipal and industrial wastes [4,5], waste heat recovery from chemical and metallurgical processes [6,7], and combustion or conversion of low quality chlorine "contaminated" fuels [8,9].…”

Abstract. -Internal attack of chromium containing alloys in mixed oxygen-chlorine environments occurs by the formation of pores which penetrate down grain boundaries of the alloys. No internal attack was detected in a binary Fe-20 %Cr alloy at 1200 K in environments containing 2500 ppm C12. The rate of internal attack of alloy 800H in such environments was increased by replacing the O2 in the gas by C 0 2 . In mixed oxygen-carbon-chlorine environments, the internal attack occurs by selective chlorination of chromium carbides which precipitate along the grain boundaries.
