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 ShipmentCommerce clause
