Abstract: The microstructures of steels are altered when exposed to high working temperatures for long periods, which results in varied physical and chemical proprieties. This study evaluates the erosive wear behavior of ASTM A106 steel after it is exposed to high temperatures for long durations. Samples of normalized ASTM A106GrB steel were placed in a muffle furnace at 530 and 630 °C for 50, 100, and 200 h. The erosive wear test was conducted at a speed of 20 m/s for 30 min at 450 °C with an incidence angle of 30°. Ir…
