EN 10270-2 Grade TDSiCr oil quenched and tempered
EN 10270-2 Grade TDSiCr oil quenched and tempered introduction
The round, oil hardened and tempered alloy steel wire TDSiCr with medium fatigue strength and high 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: IS TDSiCr, ISO TDSiCr, DIN TD SiCr, AFNOR TDSiCr, BS TDSiCr
