Abstract

In order to study the effect of shot peening on water vapor oxidation resistance of austenitic stainless steel TP347H, spare reheater tube of a certain power plant is made into the experimental sample, and part of the samples have been shot blasted, the experimental samples are used to do the contrast test of high temperature water vapor oxidation using a laboratory high temperature steam oxidation device. The oxidation kinetics equations are obtained by oxidation kinetics experiments, results show that in the high temperature steam environment of 800 within 80h, oxidation kinetics equation of TP347H steel comply with the laws of parabola. oxidation membrane surface and cross-section was analyzed by using SEM, EDX and GIXRD and the results show that shot peening changes the oxide layer of phase composition and the structure of oxidation layer, and significantly improve the oxidation resistance of TP347H steel.
