A group of low chromium content tubing steels with additional amounts of silicon were erosion-corrosion tested in air at temperatures to 850°C with angular shaped erodent particles and FBC bed material. In previous tests using round shape erodent particles, these modified steels formed highly segmented scales which resulted in considerably lower erosion-corrosion metal wastage rates than occurred in typical silicon content low chromium steels. The same type of behavior occurred when angular shaped particles were used but to a lesser extent. The angular shaped particles resulted in thin scales that directly involved the substrate metal in the metal wastage process.
