Abstract
In this work, the erosion behavior of hardfaced SS310 steel, used for pulverized coal burner nozzle, is studied using Air Jet Erosion Testing Rig. The hardfacing was done with SMAW by varying the molybdenum (Mo) alloying element percentage from 0 to 5 wt.% in hardfacing electrode powder. Microhardness, microstructure, and SEM/EDS analysis was done to analyze the structural uniformity of hardfaced steel samples. It was found that by hardfacing, the elements’ distribution become uniform and the structure of the hardfaced steel become dense and bright. The microhardness of the hardfaced steel was decreased as the Mo content added up to 5 wt.% in electrode powder. The hardfacing shows ductile behavior of erosion at room as well as at 400 °C temperature.
