Forged Gear Blanks 34CrNiMo6 20MnCr5 18CrNiMo7-6 Guangda Xinsheng
Higher quality and increased strength and wear in forged gear blanks is achieved from contoured grain flow, reduced grain size and thermal processing that improves mechanical properties and metallurgical soundness from the open die forging process. All of our forgings are rough machined to allow for final machining.

Alloy Steel Forgings procedure
Orging 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
High-precision dimensional tolerance;Excellent mechanical properties;Produce different dimension based on customer’s requirements;Advanced manufacture equipments and inspection devices;Excellent technical personality;Control the production procedure strictly;Pay attention on the package protection;Quality full service.
