The results from steam oxidation test on Tempaloy A-3 tube at 650℃for up to 1 000 hshow that the oxide scale of Tempaloy A-3 was with two-layer structure:Fe3O4 outer layer and Cr2O3 inner layer.The protective oxide scale was formed at early stage of oxidation
then it grew slowly in the subsequent oxidation process.The steam oxidation resistance of Tempaloy A-3 was obviously better than that of TP347 HFG.In addition
the Tempaloy A-3 had good high temperature strength and aging toughness
therefore it could be a substitute for HR3 Cin high temperature heating environments.
