High Temperature Cyclic Impact/Abrasion Testing of Boiler Steels

In the present study the high temperature impact/abrasion resistance of several boiler steels which are used in Estonian power plants were determined experimentally using the High Temperature Cyclic Impact Abrasion Test (HT-CIAT) at 500 and 600 degrees C. Results indicate a strong dependence of the wear resistance on the materials microstructure and formation of the mechanically mixed layer with incorporated abrasive particles.
