Many of the corrosion problems in air pollution control equipment have been solved by the use of highly alloyed materials. However, these alloys are not usually chosen at the design stage. Highly alloyed materials are defined in this paper as nickel-base alloys or iron-base alloys containing 35 percent or more alloying elements. This paper describes several case histories of the use of these alloys mostly installed as maintenance items after the original materials of construction failed. Non-metallic coatings over steel or lower alloyed materials usually comprised the unsatisfactory original materials of construction. The use of a low original cost alloy or coating material, that later proves unsuitable, may end up as the most expensive material choice when replacement or repair and production loss through downtime are considered.
