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
