(Main)Heat-treatable steels, alloy steels and free-cutting steels - Part 4: Free-cutting steels (ISO 683-4:2016)
Heat-treatable steels, alloy steels and free-cutting steels - Part 4: Free-cutting steels (ISO 683-4:2016)
ISO 683-4:2016 gives the technical delivery requirements for semi-finished products (e.g. blooms, billets, slabs), bars and wire rod, manufactured from the free-cutting steels listed in Table 2 and supplied in one of the treatment conditions given for the different types of products in Table 1, rows 2 to 4.
It covers three groups of free-cutting steels for mechanical purposes as listed in Table 2, namely
a) not intended for heat treatment,
b) suitable for case-hardening, and
c) suitable for quenching and tempering.
Free-cutting steels are often used as bright bars. For these products, refer to ISO 683‑18.
In special cases, variations in these technical delivery requirements or additions to them can form the subject of an agreement at the time of enquiry and order (see 5.2 and Annex B).
In addition to ISO 683-4:2016, the general technical delivery requirements of ISO 404 are applicable.
Für eine Wärmebehandlung bestimmte Stähle, legierte Stähle und Automatenstähle - Teil 4: Automatenstähle (ISO 683-4:2016)
Dieser Teil der ISO 683 enthält die technischen Lieferbedingungen für Halbzeug (z. B. Vorblöcke, Knüppel
Brammen), Stäbe und Walzdraht, hergestellt aus Automatenstählen nach Tabelle 2, welche in einem der
Tabelle 1, Zeilen 2 bis 4 für die verschiedenen Erzeugnisformen angegebenen Wärmebehandlungszustand
geliefert werden.
Dieser Teil der ISO 683 enthält die im Folgenden aufgeführten drei Gruppen von Automatenstähle für
mechanische Anwendungen nach Tabelle 2:
a) nicht für eine Wärmebehandlung bestimmte Stähle,
b) Einsatzstähle und
c) Vergütungsstähle.
Automatenstähle werden häufig als Blankstäbe verwendet. Für diese Erzeugnisse ist Bezug auf die ISO 683-
18 zu nehmen.
In Sonderfällen können bei der Anfrage und Bestellung Abweichungen von oder Zusätze zu diesen
technischen Lieferbedingungen vereinbart werden (siehe 5.2 und Anhang B).
Zusätzlich zu diesem Teil der ISO 683 sind die allgemeinen technischen Lieferbedingungen nach ISO 404
anzuwenden.
Aciers pour traitement thermique, aciers alliés et aciers pour décolletage - Partie 4: Aciers pour décolletage (ISO 683-4:2016)
La présente partie de l'ISO 683 spécifie les conditions techniques de livraison des demi-produits (par exemple, blooms, billettes, brames), barres, fils machine, fabriqués à partir d'aciers de décolletage figurant dans le Tableau 2 et livrés dans l'un des états de traitement thermique donnés pour les différents types de produits dans le Tableau 1, lignes 2 à 4.
La présente partie de l'ISO 683 concerne trois familles d'aciers de décolletage à des fins mécaniques énumérées dans le Tableau 2, à savoir:
a) les aciers non destinés à un traitement thermique;
b) les aciers destinés à un traitement de trempe après cémentation, et;
c) les aciers destinés à un traitement de trempe et de revenu.
Les aciers de décolletage sont souvent utilisés sous forme de barres calibrées. Pour ces produits, voir l'ISO 683‑18.
Dans certains cas particuliers, il est possible de déroger aux présentes conditions techniques de livraison ou d'en ajouter d'autres, à condition d'en convenir au moment de l'appel d'offres et de la commande (voir 5.2 et Annexe B).
En plus de cette partie de l'ISO 683, les conditions générales techniques de livraison de l'ISO 404 sont applicables.
Toplotno obdelana, legirana in avtomatna jekla - 4. del: Avtomatna jekla (ISO 683-4:2016)
ISO 683-4:2016 podaja tehnične dobavne zahteve za polizdelke (npr. bloke, palice, plošče), drogove in valjane žice, izdelane iz avtomatnih jekel, navedenih v preglednici 2, in dobavljenih v enem od stanj obdelave, podanih za različne vrste izdelkov v preglednici 1, vrstice 2 do 4.
Zajema tri skupine avtomatnih jekel za mehanske namene, kot je navedeno v preglednici 2, in sicer
a) nenamenjene za toplotno obdelavo,
b) primerne za cementiranje ter
c) primerne za poboljšanje.
Avtomatna jekla se pogosto uporabljajo kot svetli drogovi. Za te izdelke glej ISO 683‑18.
V posebnih primerih so lahko različice teh splošnih tehničnih dobavnih zahtev ali dodatki k njim predmet sporazuma v času povpraševanja in naročila (glej točko 5.2 in dodatek B).
Poleg standarda ISO 683-4:2016 se uporabljajo tudi splošne tehnične dobavne zahteve standarda ISO 404.
