In recent years, a considerable amount of discussion has taken place about the environmental problems on a worldwide scale. Environmental load gases, such as CO2, SOx, and NOx, are generated in the manufacturing process of metal materials, which cause environmental destruction. Thus, the generation of environmental load gases in the process of manufacturing various heat-resistant materials was estimated using an environmental load calculation system developed by Halada et al., and the indicator of the optimum material selection is discussed from the viewpoint of environmental conformity.Research was conducted with regard to the relationship between the environmental load gases of heat-resistant materials, and mechanical properties at high temperature were also investigated. Consequently, it was understood for the heat-resistant materials with many kinds of additional alloy element that there are generating considerable amount of the environmental Consequently, it was understood that heat-resistant materials with many kinds of additional alloy elements generate a considerable amount of environmental load gases during the manufacturing process. Moreover, the guidelines for material selection were established for the design of an apparatus used at high temperature on the basis of the optimal environmental conformity.
