.... The turbine vanes as stationary hot parts are not subjected to centrifugal loads and can be made of high-strength-cast cobalt-based superalloys. Cobalt-based superalloys such as FSX 414 show good resistance to hot corrosion and good weldability. Iron–nickel-based superalloys, e.g., Inconel 718 are typically...
