The influence of production routes on the metal dusting behavior of UNS N06025 plate, strip and tube
conference paper
It is generally known that the production route influences the sensitivity of a material to metal dusting. In this study the different production states of UNS N06025 are compared as there are: plate deeply ground and 600 grit laboratory ground, strip as-delivered and 600 grit laboratory ground, and longitudinally welded tubes as-delivered and 600 grit laboratory ground. All samples were exposed for 7750 hours at 600°C in a 37% CO, 7% CO_2, 46% H_2, 9% H_2O atmosphere, P tot = 20 bar. The differences between the samples originating from different production routes, in terms of mass loss, pit density, pit size and pit depth, are discussed in terms of the effect of surface treatment (ground, brushed, annealed, pickled), grain size, chemical composition and sample thickness. ©2012 by NACE International.
