Abstract
— Gold dust is a surface defect that usually observed on the surface of 430 grade stainless steel. Gold dusting is characterized by sparkling appearance. They occur as small flakes of metal on the cold rolled surface elongated in the rolling direction. As this defect occurs on the surface of the component, it affects the intended application of the steel for which they have been designed. Further loss of material in the powder form can affect the mechanical properties of the component. The defect is analyzed through optical and Scanning electron microscope with EDAX. From the results it is observed that the defect is due to sensitization. The paper is based on the work to identify the sources of the defect and solutions to overcome this defect.
