Process procedure:
Forging process flow quality control:

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