rothe erde® impress with their performance, which they owe to the seamless rolling process. Warm treatment generates the many mechanical properties demanded of the rings. Besides the normalising, the tempering and soft annealing of the rings enables programmed processes for all (special) materials to comply with the specific time-temperature provisions most accurately.
