Creep resisting steels, nickel and cobalt alloys
1.1 This European Standard covers the grades of wrought steels and alloys listed in Table 1 and Table 2, which are usually employed for components and equipment, for which the main requirement is their creep resistance under mechanical long-time stressing at temperatures above 500 C.
NOTE Heat resisting grades given in EN 10095 [9] may also be used for similar applications if so agreed.
1.2 This European Standard specifies the technical delivery conditions for semi-finished products, for hot or cold rolled sheet/plate and strip, hot or cold formed (cold drawn) bars, rods, wire and sections.
1.3 The general technical delivery conditions specified in EN 10021:2006 apply in addition to the specifications of this European Standard, unless otherwise specified in this European Standard.
1.4 This European Standard does not apply to components manufactured by further processing the product forms listed in 1.2 with quality characteristics altered as a result of such further processing.
1.5 This European Standard shall not be used for aerospace and pressure purposes.
1.6 For steels and alloys with similar chemical composition, but intended for different applications, see the Bibliography.
Warmfeste Stähle, Nickel- und Cobaltlegierungen
1.1 Diese Europäische Norm gilt für die in den Tabellen 1 und 2 aufgeführten Sorten von Stählen und
Legierungen, die üblicherweise für Erzeugnisse verwendet werden, bei denen die Langzeitwarmfestigkeit
unter mechanischer Beanspruchung bei Temperaturen oberhalb 500 °C die Hauptanforderung darstellt.
ANMERKUNG Falls vereinbart, dürfen auch hitzebeständige Stähle nach EN 10095 [9] für ähnliche Anwendungen
verwendet werden.
1.2 Diese Europäische Norm legt die technischen Lieferbedingungen für Halbzeug, warm- oder kaltgewalztes
Blech und Band, warm- oder kaltgeformte (kaltgezogene) Stäbe, Walzdraht, gezogenen Draht und
Profile fest.
1.3 Zusätzlich zu den Angaben dieser Europäischen Norm gelten, sofern in dieser Norm nichts anderes
festgelegt ist, die in EN 10021 wiedergegebenen allgemeinen technischen Lieferbedingungen.
1.4 Diese Europäische Norm gilt nicht für die durch Weiterverarbeitung der in 1.2 genannten Erzeugnisformen
hergestellten Teile mit fertigungsbedingten abweichenden Gütemerkmalen.
1.5 Diese Europäische Norm darf nicht für Luft- und Raumfahrt- sowie Druckbehälteranwendungen benutzt
werden.
1.6 Für Stähle und Legierungen mit ähnlicher chemischer Zusammensetzung, jedoch anderem Verwendungszweck,
siehe Abschnitt Literaturhinweise.
Aciers et alliage à base de nickel et de cobalt résistant au fluage
1.1 La présente Norme européenne traite des nuances d'aciers et d'alliage corroyés énumérés dans les Tableaux 1 et 2 qui sont généralement employés pour la fabrication de pièces et de matériels, dont l'exigence principale porte sur la résistance au fluage lorsqu'elles subissent une contrainte de longue durée à des températures supérieures à 500 °C.
NOTE Les nuances d'aciers réfractaires données par l'EN 10095 [9] peuvent, si cela fait l'objet d'un accord, être utilisées pour des applications similaires.
1.2 La présente Norme européenne spécifie les conditions techniques de livraison des demi-produits, des tôles/bandes et feuillards laminés à chaud ou à froid, des barres, du fil machine, des fils et des profils transformés à chaud ou à froid (étirés à froid).
1.3 Sauf spécification contraire dans le présent document, les conditions techniques générales de livraison spécifiées dans l'EN 10021 s'appliquent en plus des spécifications de la présente Norme européenne.
1.4 La présente Norme européenne ne s'applique pas aux éléments fabriqués par transformation ultérieure de produits énumérés en 1.2, qui aurait pour effet de modifier les caractéristiques de qualité de ces produits.
1.5 La présente norme européenne n'est pas destinée à être utilisée dans le cadre d'applications aérospatiales ou sous pression.
1.6 Pour les aciers et alliages ayant une composition chimique analogue mais destinés à d'autres applications, voir la bibliographie.
