Forging process flow quality control:

1. Raw material steel ingot into warehouse(test the chemical content)
2. Cutting→ Heating(Furnace temperature 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
