    Process procedure:

    Forging process flow quality control:

    1. Raw material steel ingot into warehouse(test the chemical content)
    2. Cutting→ Heating(Furnace temperture test)
    3. Heat treatment after forging(Furnace temperture test) Discharge the furnace(blank inspection)
    4. Machining→ Inspection(UT,MT,Visal diamention, hardness)
    5. QT→ Inspection(UT, mechanical properties, hardness, grain size)
    6. Finish machining→ Inspection (dimension)
    7. Packing and Marking(steel stamp, mark)→ Storage Shipment
