Retaining rings
We have been manufacturing cap rings for turbo generators for over 100 years and are constantly developing them further. This has made us the world market leader in this segment.
To produce our cap rings, the steel is first remelted in ESR systems and then shaped into the correct form in open-die forging. The rings are then pre-turned, heat-treated, cold expanded, stress-relieved, turned and tested.
We manufacture the following dimensions:
Austenite
We use the austenitic steel P900 (material number/DIN code: 1.3816, ASTM A 289, Class C, X8CrMnN18-18) developed by us to ensure that our cap rings can withstand the enormous centrifugal forces.
