Production Procedures: 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,Visal diamention, hardness)→ QT→ Inspection(UT, mechanical properties, hardness, grain size)→ Finish machining→ Inspection (dimension)→ Packing and Marking(steel stamp, mark)→ Storage Shipment  Advantage: Excellent mechanical properties, High-precision dimensional tolerance, Control the production procedure strictly, Advanced manufacture equipment and inspection devices, Excellent technical personality, Produce different dimension based on customer’ s requirements, Pay attention on the package protection, Quality full service. Application Industries: Oil&gas extraction, wind power generation, metallurgical machinery, engineering machinery, shipbuildingindustry, pressure vessels, nuclear power, etc.
