Under some inexactly defined conditions, steels and alloys are attacked by atmospheres resulting from oxidation of hydrocarbon. In a fixed-bed catalytic system for dehydrogenation of butane the metal loss which contaminates the catalyst with a fine oxide dust causes undesirable side effects. The way in which the metal loss occurs is described and the effects of alloying agents on both laboratory tests and actual equipment are mentioned. Some examples of metal dusting give a clue to the mechanism of metal loss, but are not complete enough to define it fully. 4.4.6
