Forged disc blanks are produced as heavy-duty circular preforms, which are subsequently machined into discs, flanges, rotors, covers, and other circular components.
At Kingrail Parts, we utilize open-die forging processes to manufacture custom forged discs and blanks. We work with a wide range of high-performance materials to produce custom forged discs and blanks tailored to your specific diameter and thickness requirements.
Specifications
Typical Materials: Carbon steel, alloy steel, stainless steel, and machining-grade disc steel.
Typical Size Range: Outer diameter, thickness, facing allowance, bore allowance, and rough machining scope are determined based on part geometry.
Supply Conditions: Depending on project scope, products can be supplied as-forged, heat-treated, rough-machined, semi-finished, or fully finished.
Machining Scope: Facing, outer diameter (OD), bore diameter, drilling reference, template blanks, thickness control, and pre-machined blanks.
Inspection Options: Ultrasonic Testing (UT), Magnetic Particle Testing/Liquid Penetrant Testing (as applicable), Positive Material Identification (PMI), hardness testing, mechanical property testing, dimensional inspection, and third-party witnessing.
Typical Applications: Heavy-duty circular machined parts; cover plates and support discs; equipment blanks; general disc machining applications.
Why Choose Kingrail Parts:
* Consistent Circular Blank Quality – Forged discs and tubesheets provide a more stable material foundation for heavy-duty machining compared to plate stock.
* Thickness and Face Control – The forging process ensures superior thickness consistency and provides ample material on the faces for machining critical components.
* Pressure Equipment Suitability – Tubesheets and heavy-duty discs are available for heat exchanger and vessel projects requiring documentation and NDT support.
* Project-Specific Materials – Carbon steel, chrome-moly steel, stainless steel, duplex steel, and other project-specific materials can be supplied according to drawings and specifications.
Typical Applications
* Heavy-duty circular machined parts
* Cover plates and support discs
* Equipment blanks
* General disc machining applications
Supply Scope
Forged disc blanks can be supplied as-forged, heat-treated, rough-machined, or semi-finished, depending on the customer's specific process requirements. If the project requires stricter dimensional control, additional processing—such as OD/ID/face machining, journal machining, boring, or drilling—can be performed prior to shipment.
