Abstract The presence of easy-diffusion paths is veryimportant for fast formation or healing of a protectiveCr-rich oxide scale for resistance of chromia-formingsteels against metal dusting. Such easy-diffusion paths, grain boundaries, subboundaries, anddislocations are provided by a fine-grainmicrostructure, cold and/or surface working —polishing, grinding, machining, sand blasting. Theirimportance and effectiveness are demonstrated by various laboratory resultsand also by a failure case and their appearance is shownby TEM studies on ground steel specimens.
