(Main)Steel wire for mechanical springs - Part 3: Stainless spring steel wire
Steel wire for mechanical springs - Part 3: Stainless spring steel wire
1.1 This European Standard applies to the grades of stainless steels listed in Table 1, which are usually used in the cold drawn condition in the form of wire of circular cross-section up to 10,00 mm in diameter, for the production of springs and spring parts that are exposed to corrosive effects and sometimes to slightly increased temperatures (see A.1).
1.2 In addition to the steels listed in Table 1 certain of the steel grades covered by EN 10088-3 e.g. 1.4571, 1.4539, 1.4028 are also used for springs, although to much lesser extent. In these cases the mechanical properties (tensile strength, etc.) should be agreed between purchaser and supplier. Similarly, diameters between 10,00 mm and 15,00 mm may be ordered according to this standard; in this case the parties should agree upon the required mechanical characteristics.
1.3 In addition to this European Standard the general technical delivery requirements of EN 10021 are applicable.
Stahldraht für Federn - Teil 3: Nichtrostender Federstahldraht
Diese Europäische Norm gilt für die nichtrostenden Stähle nach Tabelle 1, die üblicherweise im
kaltgezogenen Zustand in Form von Draht mit kreisförmigem Querschnitt bis 10,00 mm Durchmesser für die
Fertigung von Federn und federnden Teilen, die Korrosionseinflüssen und mitunter leicht erhöhten
Temperaturen (siehe A.1) ausgesetzt sind, verwendet werden.
1.2 Außer den Stählen nach Tabelle 1 werden auch einige Sorten nach EN 10088-3, zum Beispiel 1.4571,
1.4539, 1.4028, für Federn verwendet, allerdings in wesentlich geringerem Umfang. In diesen Fällen sind die
mechanischen Eigenschaften (Zugfestigkeit usw.) zwischen Besteller und Lieferer zu vereinbaren. Ähnlich
können Durchmesser zwischen 10,00 mm und 15,00 mm nach dieser Norm bestellt werden; in diesem Falle
müssen die Beteiligten die benötigten mechanischen Eigenschaften vereinbaren.
1.3 Zusätzlich zu dieser Europäischen Norm gelten die allgemeinen technischen Lieferbedingungen nach
EN 10021.
Fils en acier pour ressorts mécaniques - Partie 3: Fils en acier inoxydable
1.1 Cette présente norme européenne de l'EN 10270 s'applique aux nuances d'acier inoxydable répertoriées au Tableau 1, qui sont habituellement utilisées à l'état tréfilé à froid sous forme de fils de section transversale circulaire d'un diamètre pouvant atteindre 10,00 mm, destinés à la fabrication de ressorts et de parties de ressorts soumis à des effets corrosifs et parfois à des températures moyennement élevées (voir A.1).
1.2 Outre les aciers énumérés au Tableau 1, certaines des nuances d'acier couvertes par l'EN 10088-3, telles que 1.4571, 1.4539, 1.4028 sont également utilisées dans une moindre mesure pour la fabrication de ressorts. Dans ces cas, il convient que les caractéristiques mécaniques (résistance à la traction, etc.) fassent l'objet d'un accord entre l'acheteur et le producteur. De la même manière, il est possible de commander des fils dont les diamètres sont compris entre 10,00 mm et 15,00 mm, sur la base de la présente Norme ; dans ce cas, il convient que les parties s'entendent sur les caractéristiques mécaniques requises.
1.3 Les conditions techniques générales de livraison de l'EN 10021 s'ajoutent aux dispositions de cette norme européenne.
Jeklena žica za vzmeti - 3. del: Nerjavna jeklena žica za vzmeti
Ta evropski standard velja za vrste nerjavnih jekel, naštetih v preglednici 1, ki se ponavadi uporabljajo v hladno vlečenem stanju v obliki žice s krožnim prečnim prerezom do 10,00 mm v premeru za proizvodnjo vzmeti in vzmetnih delov, izpostavljenih korozivnim učinkom in včasih nekoliko povišanim temperaturam (glej A.1). Poleg jekel, naštetih v preglednici 1, se za vzmeti uporabljajo tudi nekatere vrste jekel, ki jih zajema EN 10088-3, npr. 1.4571, 1.4539, 1.4028, vendar v precej manjšem obsegu. V teh primerih se morata o mehanskih lastnostih (natezna trdnost, itd.) dogovoriti kupec in dobavitelj. Podobno se v skladu s tem standardom lahko naročajo premeri med 10,00 mm in 15,00; v tem primeru se morata stranki dogovoriti o potrebnih mehanskih karakteristikah. Poleg tega evropskega standarda veljajo splošne tehnične dobavne zahteve EN 10021.
