Many industrial processes involve the exposure of materials to high-temperature environments which contain aggressive species such as chlorine. Little information concerning high-temperature corrosion resistance at temperatures greater than 760°C (1400°F) in these halogen-bearing environments has been available to guide materials selection. This study describes the behavior of various high-temperature materials subjected to both chlorine- and hydrogen chloride-bearing environments at 900°C (1650°F). Both weight-change data and metallographic evaluation of the modes of attack are presented, together with analysis of corrosion products by various analytical techniques. The possible relationships between alloy chemistry and performance are discussed.
