Coal fired power plants use high temperature and high pressure steam to make electricity. With the steam parameter improved to ultra-super critical
the steam oxidation becomes much more serious. Heat resistant steels for coal- fired power plants mainly include low alloy heat resistant steels
9% Cr martensitic heat resistant steels and 18Cr-8Ni austenitic heat resistant steels. In this paper
the steam-oxidation behavior of the three kinds of heat-resistant steels is reviewed
and the kinetics and the structure characteristics of the oxide scale are introduced. The methods of improving steam oxidation resistance are summarized. The methods for avoiding possible oxidation problems in service exposure of the three kinds of materials are suggested
