EN ISO 4957:1999

Tool steels (ISO 4957:1999)

This international standard covers the grades of wrought tool steels listed in tables 2, 4, 6 and 8, namely: a) unalloyed cold-work tool steels (see table 2); b) alloyed cold-work tool steels (see table 4); c) alloyed hot-work tool steels (see table 6); d) high-speed steels (see table 8). If not stated in the following, this international standard applies to all types of hot-rolled, forged or cold-drawn products which are supplied in one of the surface and heat-treatment conditions given in 5.1.2 and table 1.

Werkzeugstähle (ISO 4957:1999)

Diese Internationale Norm gilt für die folgenden Sorten aus Werkzeugstahl: a) unlegierte Kaltarbeitsstähle; b) legierte Kaltarbeitsstähle; c) legierte Warmarbeitsstähle; d) Schnellarbeitsstähle; Soweit nicht anders angegeben, gilt diese Internationale Norm für alle Arten warmgewalzter, geschmiedeter, kaltgezogener oder kaltgewalzter Erzeugnisse, die in einem der in 4.1.2 und Tabelle 1 aufgeführten Oberflächen- und Wärmebehandlungßustände geliefert werden. Erzeugnisse nach dieser Internationalen Norm dürfen auch pulver- metallurgisch hergestellt werden.

Aciers à outils (ISO 4957:1999)

La présente Norme internationale spécifie les nuances des aciers à outils corroyés, à savoir:a) aciers à outils non alliés pour travail à froid;b) aciers à outils alliés pour travail à froid;c) aciers à outils alliés pour travail à chaud;d) aciers rapides.Sauf spécification contraire, la présente Norme internationale s'applique à tous les types de produits laminés à chaud ou à froid, forgés, ou étirés à froid et qui possèdent à la livraison l'un des états de surface et de traitement thermique spécifiés en 4.1.2 et dans le Tableau 1.Les produits mentionnés dans la présente Norme internationale peuvent être produits par la métallurgie des poudres.NOTE 1 Les Tableaux 2, 4, 6 et 8 ne prennent en compte que les aciers qui ont acquis une certaine renommée internationale, ce qui ne signifie pas toutefois qu'ils soient disponibles dans tous les pays industriels. De plus, un certain nombre d'autres aciers à outils sont décrits dans des normes régionales, nationales ou d'entreprises.NOTE 2 Lorsque la résistance à la chaleur des outils est un facteur d'une importance particulière, comme par exemple dans le cas des outils pour le façonnage à chaud du verre, il convient de baser le choix du matériau sur l'ISO 4955 ou l'ISO 9722.En complément de la présente Norme internationale, les conditions techniques générales de livraison définies dans l'ISO 404 sont applicables.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
