EN 10270-2 Grade TDC oil quenched and tempered
EN 10270-2 Grade TDC oil quenched and tempered introduction
The round, oil hardened and tempered carbon steel wire TDC with medium fatigue strength and low 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.
Equivalent material: AS 1472, IS TDC, ISO TDC, DIN TD C, AFNOR TDC, BS TDC
