DIN 17223-2 E : 1990

Specifies requirements for oil quenched and tempered round wire, made of carbon or alloy steel, suitable for the manufacture of springs that are mainly stresses in torsion (e.g. compression or extension springs) and, in some cases, also in bending (e.g. leg springs designed for operation in the fatigue limit or finite life range) (cf. Appendix A). Normally, carbon steel wire is used for applications at ambient temperature and alloy steel wire for those at elevated temperature.
