The Post-forging Heat Treatment Process of 9Cr Martensitic Heat-resistant Steel

The Post-forging Heat Treatment Process of 9Cr Martensitic Heat-resistant Steel

9Cr martensitic heat-resistant steel is an important candidate material for ultra-supercritical steam turbine rotors. Due to the large size of the rotor forgings， there is a greater tendency for microstructure inheritance. The microstructure and mechanical properties of 9Cr martensitic heat-resistan...
