Abstract
In order to study the effect of minor Zr on the oxidation resistance and the mechanical properties of nickel-saving austenitic heat-resistant cast steel, the oxidation resistance at 900 °C and the tensile properties at room temperature and at 900 °C of Zr-containing and Zr-free steels were carried out. The results showed that the addition of 0.011% Zr could slightly reduce the oxidation rate and improve the oxidation resistance of Zr-containing steel. In addition, the tensile properties of Zr-containing steel at room temperature and at 900 °C were significantly improved. Brittle fracture occurred in two experimental steels at both temperatures, and brittle characteristics appeared in the fractures.
