(Main)Surface quality classes for hot-rolled bars and wire rod (ISO 9443:2018)
Surface quality classes for hot-rolled bars and wire rod (ISO 9443:2018)
This International Standard specifies technical delivery requirements for the surface quality of round bars, squares, hexagons and wire rod in the hot rolled condition with nominal diameters dN from 5 mm to 200 mm. By agreement between manufacturer and purchaser, this International Standard may also be applied to other special profiles. This International Standard applies particularly to steels for engineering and structural applications and, by agreement, may also be applied to tool steels.

Dieses Dokument enthält die technischen Lieferbedingungen für die Oberflächengüteklassen für Rundstäbe, Vierkantstäbe, Sechskantstäbe und Walzdraht im warmgewalzten Zustand mit Nenndurchmessern dN von 5 mm bis 200 mm. Dieses Dokument kann auch für Blankstahl und Werkzeugstahl herangezogen werden, sofern dies zum Zeitpunkt der Anfrage und Bestellung zwischen Hersteller und Besteller vereinbart war.
Nach Vereinbarung zwischen Hersteller und Besteller kann dieses Dokument auf andere Sonderprofilformen angewendet werden.
Dieses Dokument gilt vor allem für Stähle, die im Maschinenbau und im Bauwesen angewendet werden.
Dieses Dokument enthält keine Anforderungen an die zulässige Tiefe der Randentkohlung.
ANMERKUNG Die Bestimmung der Tiefe der Randentkohlung ist in ISO 3887 beschrieben.
Die Normen für die Lieferbedingungen für Stabstahl und Walzdraht können die Anwendung einzelner Oberflächengüteklassen dieses Dokumentes ausschließen. Dies können ebenfalls Anforderungen an die Oberflächenqualität sein, die von diesem Dokument abweichen. In diesen Fällen gelten die Anforderungen in den Normen für die Lieferbedingungen.
Classes de qualité de surface des barres et fils-machine laminés à chaud (ISO 9443:2018)
Le présent document spécifie les spécifications techniques de livraison relatives à la qualité de surface des barres de section ronde, carrée, hexagonale et du fil machine en acier laminé à chaud avec des dimensions nominales dN compris entre 5 mm et 200 mm. Le présent document est applicable aux produits transformés à froid et aux aciers à outils, si cela est convenu au moment de l'appel d'offres et de la commande entre le fabricant et l'acheteur.
Par accord entre le fabricant et l'acheteur, le présent document peut également être appliquée à d'autres profilés spéciaux.
Le présent document est plus particulièrement applicable aux aciers à usages mécaniques, et aux aciers de construction.
Le présent document ne renferme aucune spécification relative à la profondeur admissible de décarburation.
NOTE La détermination de la profondeur de décarburation est décrite dans l'ISO 3887.
Les normes de matériaux pour barres et fil machine en acier peuvent exclure l'utilisation de l'une quelconque des classes de qualité de surface prévues dans le présent document. Elles peuvent également renfermer des spécifications pour la qualité de surface divergentes par rapport à ce présent document. Dans ce cas, les spécifications de la norme de matériau prévalent.
Kakovostni razredi površin vroče valjanih drogov in valjane žice (ISO 9443:2018)
Ta mednarodni standard določa tehnične dobavne zahteve za kakovost površin okroglih, kvadratnih in šesterokotnih drogov ter valjane žice v vroče valjanem stanju z nazivnimi premeri dN od 5 mm do 200 mm. Na podlagi dogovora med proizvajalcem in kupcem se ta mednarodni standard lahko uporablja tudi za druge posebne profile. Ta mednarodni standard se uporablja zlasti za jekla, namenjena za gradbeno in konstrukcijsko uporabo, po dogovoru pa se lahko uporablja tudi za orodna jekla.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
