Want to keep this datasheet? Save it now in your required format


The round, oil hardened and tempered alloy steel wire TDCrV with medium fatigue strength and medium tensile strength is used mainly for torsion loaded springs (tension and compression springs). It will be delivered in rings, in coils or as bars and, if not otherwise arranged, thin oiled. Der runde, ölschlußvergütete Federdraht der Sorte TDCrV aus legiertem Stahl wird vorzugsweise verwendet für mittlere torsionsbeanspruchte Federn (Zug- und Druckfedern) oberhalb Raumtemperatur. Der Draht wird in Ringen, auf Spulen oder in Stäben und, wenn nicht anders vereinbart, im leicht geölten Zustand geliefert.
