The Process As Follow: ingot → heat → forging → heat treatment(normalizing+tempering) → inspection → rough machining → UT → 2nd heat treatment → finishing machining → inspection .
Quality Control: UT,MT,RT,PT,chemical composition test,mechanical property test,etc.
Heat Treatment: Normalize,Quenching,Tempering,Anealled.
Surface Treatment: painting,plating,polishing,black oxide,transparent anti-rust oil.
Inspection: Besides our in-house inspecion, you could also choose a third party inspection.
Certificate: 1, Raw material certificate(material chemical compositon)
2, Heat treatment sheet report
3, Dimension inspection report
4, UT test report
Packing: Seaworthy plywood packaged on stell pallets or as customer's request
Delivery Date: Decided by the amount and dimensions of products. Usually we control the large diameter rings' delivery time within 5 weeks after we receive your formal order.
Competitive Advantage: Quality control and management to the whole produce process, including ingot smelting,forging, heat treatment, machining and strictly final inspection prior to delivery.
