Walzdraht, Stäbe und Draht aus Kaltstauch- und Kaltfließpress-stählen – Teil 4: Technische Lieferbedingungen für Vergütungsstähle
European Standard EN 10263-4 : 2001 has the status of a DIN Standard.
A comma is used as the decimal marker.
National forewordThis standard has been prepared jointly by ECISS/TC 15 ‘Wire rod – Qualities, dimensions, tolerances andspecific tests’, ECISS/TC 23 ‘Steel for heat treatment, alloy steels and free-cutting steels – Qualities’, andECISS/TC 30 ‘Steel wires’.The responsible German body involved in its preparation was the Normenausschuss Eisen und Stahl (Steeland Iron Standards Committee), Technical Committee Kaltstauch- und Kaltfließpressstähle.For ease of reference, the table overleaf correlates the material designations/symbols used in DIN 1654-4with those given in the present standard.
