Product Description

Name:Forging s355 st52 sleeve bushing/ forged steel sleeve bushing

The heavy forging: forged ring, shaft, roller, flange, or gear is widely used for various industries For example: Metallurgy, mining, power station and so on. The manufacturing equipment is 185MN or 100MN hydraulic press, the forging ratio >4.5, 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 →2nd Heat treatment →finishing machining →Inspection
