Heat-resistant steels and superalloys are the main heat-treated material tooling, its quality and performance components and impurities have great contacts, and important factor in determining the material composition and impurity content is the smelting process. Thus we conclude that choosing the right smelting process is to ensure that heat-resistant steel and high temperature alloys has important means of performance.

Then look to focus their smelting process, in addition to some low-alloy pearlitic heat-resistant steel, most of the heat-resistant steel and high temperature alloys are melted in an electric arc furnace or induction excavation. In order to further improve the quality and reduce the content of impurities and gas, many heat-resistant steel casting vacuum melting, remelting, zone melting, refining and other methods.
Smelting out of heat-resistant steel and high-temperature alloy materials needed after casting, plastic deformation, heat treatment, welding, machining and other processing techniques, where every aspect of the operation, there are stringent requirements must be reasonable assurance to ensure that the final product meets the requirements .
