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
7. Inspection (dimension)
8. Packing and Marking(steel stamp, mark)
9. Storage Shipment
