Elevated temperature erosion of steels

Abstract

The elevated temperature erosion behavior of several commercial ferritic and austenitic steels was determined over a range of temperatures from room temperature to 900 °C. It was determined that all the steels had constant or decreasing erosion rates as the test temperature was increased until a temperature was reached where a marked increase in erosion rate began to occur with temperature. Austenitic steels were determined to have lower erosion rates than ferritic steels and their hardness had no correlation with their erosion rate. All the steels tested eroded by the platelet mechanism of erosion.
