Zusammenfassung:Method for manufacturing flexible steel rings (32), in particular for manufacturing ring sets (31 ) for a drive belt (3) with a number of mutually nested flexible steel rings (32), which method comprises a process step (IX) wherein the rings (32) are heat treated to provide these with a nitrided surface layer. According to the present disclosure, a thickness of these nitrided surface layers of the rings (32) is actively controlled through controlling the duration of the nitriding heat treatment. L'invention concerne un procédé de fabrication d'anneaux (32) en acier flexibles, en particulier pour fabriquer des ensembles anneau (31) pour une courroie (3) d'entraînement avec un certain nombre d'anneaux (32) en acier flexibles, mutuellement nichés. Le procédé comprend une étape de traitement (IX), les anneaux (32) étant traités thermiquement afin de les doter d'une couche de surface nitrurée. Selon la présente invention, une épaisseur de ces couches de surface nitrurées des anneaux (32) est activement contrôlée par la régulation de la durée du traitement thermique de nitruration.
