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 Shipment
Commerce clause | Max weight | 50T | | MOQ | 1PC | | Delivery time | 30-50 days | | Package | plywood case,wooden pallet,steel frame | | Delivery term | FOB;CIF;CFR；DDU； | | Payment term | T/T,LC | | type of shipping | By ocean,air |
