Following is forging process of 1.6945 forging steel  turbine rotor shafts
Forging process flow quality control: Raw material steel ingot into warehouse(test the chemical content) → Cutting→ Forged process→ Post forging heat treatment(N+T)→ UT→ Rough Machining→ UT → QT→ Inspection(UT, mechanical properties, hardness, grain size)→ Grooving→ Stress relieve Tempering → Machining holding postion for rotor when HST→ HST→ Inspection (dimension)→ Packing and Marking(steel stamp, mark)→ Storage Shipment
