| Abstract: | The processing features of oxidization resistant steel in investment casting were expounded. Pouring-shell ratio principle has been proposed to overcome crack, shrinkage porosity (hole ) in thin-walled parts through controlling processing parameters, including the baking temperature, holding temperature, holding time and pouring temperature as well as temperature of liquid steel, which can increase thermo-strength ability and corrosion resistance ata high temperature as well as postponing the service life of oxidized resistant steel parts ata high temperature. |

| Keywords: | Oxidized Resistant Corrosion at High Temperature Pouring-shell Ratio Baking Temperature |
