Stress corrosion resistant rims and discs for steam turbine rotors device and method
 A formed disc for use in a low pressure rotor has a rim made of a high alloy metal of between approximately 9% and 17% chromium. The rim can be annular in shape and slide onto the perimeter of an unformed disc for the two components to be fused together, thus fabricating a formed disc. Additionally, the rim can be split into a number of components and fused together on the perimeter of a rotor disc to form a complete rim. Further, an entire disc can be made out of the high alloy metal.
