GB/T3077-1999 20CrMnMo Forged Steel Rings, Forging Parts For Pressure Vessel

Description:

The forged steel ring, including ring, flange, gear and others, is widely used for wind power pressure vessel and mining and other industries.
The forged steel ring conforms to the standard of EN, ASTM, and DIN etc.
The manufacturing equipment is 16~185MN hydraulic press, the forging ratio >4.5, the technical condition is in accordance with the standard of EN, ASTM, and DIN etc.
The product can be provided as per your drawing or specified requirements.
    
Smelting Process:EF+LF + VD

The process as  follow  :Ingot →heat → forging → Heat treatment (Normalizing+ tempering) → Inspection →rough machining→UT→2nd Heat treatment →finishing machining →Inspection
   
Applications:  The forged steel ring, including ring, flange, gear and others, is widely used for pressure vessel, wind power and mining and other industries.
