Process procedure:
Forging process flow quality control:
●  Raw material steel ingot into warehouse (test the chemical content)
●  Cutting→ Heating (Furnace temperature test)
●  Heat treatment after forging (Furnace temperature test) Discharge the furnace (blank inspection)
●  Machining→ Inspection (UT, MT, Visual dimension, hardness)
●  QT→ Inspection (UT, mechanical properties, hardness, grain size)
●  Finish machining→ Inspection (dimension)
●  Packing and Marking (steel stamp, mark)→ Storage Shipment
