Why Forged Rings?
Typical problems associated with metal rings can frequently be traced to the metal-forming process. Cast rings are often plagued with substandard strength and integrity. Rolled and welded or cut rings out from plate are susceptible to fatigue and carry excess material and processing costs.
The forging process produces rings with controlled grain flow, which gives strength and resistance to impact and fatigue not found in rings torch cut from plate or rolled and welded.
Forged Ring Advantages
- Achieving structural integrity Optimizing toughness Enabling size versatility
Weights up to 60,000 lbs. in both ferrous and non-ferrous materials. The forging process produces rings with controlled grain flow, which gives strength and resistance to impact and fatigue not found in rings torch cut from plate, or rolled and welded.
SCOT FORGE TAILORED SOLUTIONS

Our solutions are enhanced by the capabilities of our two joint ventures: Ringmasters, which allows us to provide quick lead times on rolled rings, and North American Forgemasters, which is where we have the ability to create over-sized forgings.
OPEN DIE RING PROCESS HIGHLIGHTS
To produce open die rings, material is first upset, then pierced to form an inside diameter. The ring is then drawn over a mandrel, if necessary, to achieve desired dimensions.
ROLLED RING PROCESS HIGHLIGHTS
To produce a rolled ring, a preform is made by upsetting and piercing a hole on center. This preform is then placed on a ring mill and, through radial and axial pressure, is opened up to desired dimensions.
