The boiler steel is not only required to have good corrosion resistance at low temperature, but also required to have good oxidation resistance at high temperature for components working at high temperature. Especially for the components of superheater and reheater, when they pdf fatigue life prediction of girth gear work at high temperature, they are required not easy to be oxidized and peeled. Generally, the development speed of oxidation depth at working temperature is required to be less than 0.1mm\/year. The addition of chromium, nickel, aluminum and silicon can improve the oxidation resistance of steel.
