Abstract: A spinning ring formed of steel for ring spinning and ring twisting machines is partially hardened, i.e. in a locally limited zone of the spinning ring. At this zone there is located a traveller flange having a traveller guide surface. The spinning ring is consecutively provided in such zone with an outer running-in surface, which is softer in comparison with the hardened steel, and with a hardened core. The running-in layer is provided with an outer ferro-nitride layer adjacent to which there is provided an austenitic-martensitic transition layer containing nitrogen which continuously merges into the structure of the hardened zone, and the austenitic content of which decreases towards the inside, and the hardness of which thus increases. The traveller, upon wearing-off of the ferro-nitride layer can reach the increasingly harder and more wear resistant transition zone.
