Name:Free of charge forging Sae4130 sae4140 steel output shaft for gearbox
The heavy forging: forged ring, shaft, roller, flange, or gear is widely used for various industries,For example: CZPTlurgy, mining, power station and
so on.
The manufacturing equipment is 185MN or 100MN hydraulic press, the forging ratio >4.five,the technical condition is in accordance with the standard of ASTM, EN, DIN, ASME or GB etc.
The product can be provided as per your drawing or specified requirements.
Smelting Process: EF+LF + VD+VC
The process as follow : Ingot →heat → forging → Heat treatment (Normalizing+ tempering) →Inspection →rough machining→UT →2th Heat treatment
→finishing machining →Inspection
Programs: The heavy forging: forged ring, shaft, roller, flange, or gear is widely used for various industries For example: CZPTlurgy, mining, power station and so on.
