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