Influence of particle impact conditions and temperature on erosion-oxidation of steels at elevated temperatures

► Behaviour of steels 16Mo3, T91, 304L and 253MA has been studied under particle impacts in air at 350-650 °C. ► Material loss rates for the steels increase with increases in test temperature and particle velocity. ► Angle-dependency of weight losses for the steels slightly changes with increase in temperature. ► Materials selection maps are constructed on the basis of experimental results. ► The most highly alloyed material is not necessarily the material of best performance.
