Resumen

Super 304HCu is a boiler-grade advanced austenitic stainless-steel material, used in heat exchangers for its resistance to oxidation and corrosion at high temperatures. The air jet erosion test is used to investigate the erosion behaviour of super 304HCu under various angles of impact. The samples are eroded in a test rig at different impact angles, under a constant impact velocity of 60 m/s and a particle feed rate of 3 g/min at ambient temperature, for 5 minutes. The mass loss is found to be 10 times higher at a low angle of impact (15°) than at the higher angles (>30°). The mass loss behaviour of the Super 304HCu is typical of a ductile material and the mass loss observed is compared with similar grades of stainless steel.
