The erosion tests were carried out in the MITI SUS310J1TB material used to be utility boiler, and erosion properties were considered by simulating the temperature gradient profile between bed material and specimen surface. The results obtained are as follows.
(1) The erosion tester that enables temperature gradient between bed material and specimen surface was developed.
(2) There is a maximum erosion wastage at intermediate temperature in both case of the specimen with temperature gradient and the one without temperature gradient.
(3) Cooling method change the erosion wastage curve (erosion wastage vs temperature) and lowers the peak temperature at maximum wastage.
