Hot finished steel structural hollow sections - Part 3: Technical delivery conditions for high strength and weather resistant steels

This document specifies technical delivery conditions for high strength and weather resistant hot-finished seamless, electric welded and submerged arc welded steel structural hollow sections of circular, square, rectangular or elliptical forms.
It applies to hollow sections formed hot, with or without subsequent heat treatment, or formed cold with subsequent heat treatment above 580 °C to obtain equivalent mechanical properties to those obtained in the hot formed product.
NOTE 1   The requirements for tolerances, dimensions and sectional properties are specified in EN 10210-2.
NOTE 2   The attention of users is drawn to the fact that whilst cold formed grades in EN 10219-3 can have equivalent mechanical properties to hot-finished grades in this document the sectional properties of square and rectangular hollow sections in EN 10210-2 and EN 10219-2 are not equivalent.
NOTE 3   A range of material grades is specified in this document and the user can select the grade most appropriate to the intended use and service conditions. The grades and mechanical properties of the finished hollow sections are generally comparable with those in EN 10025-4, EN 10025-5 and EN 10025-6.
NOTE 4   The requirements for seamless and welded steel structural hollow sections for use in offshore structures are covered in the EN 10225 series.
NOTE 5    Spiral welded hollow sections are expected to be used with caution in applications involving dynamic behaviour (fatigue stress) as, up to now, there is insufficient data regarding their performance.

Warmgefertigte Hohlprofile für den Stahlbau - Teil 3: Technische Lieferbedingungen für höher- und wetterfeste Stähle

Dieses Dokument legt die technischen Lieferbedingungen für warmgefertigte nahtlose, elektrisch und unterpulvergeschweißte Hohlprofile aus höher- und wetterfesten Stählen mit kreisförmiger, quadratischer, rechteckiger oder elliptischer Form fest.
Sie gilt für warmgefertigte Hohlprofile mit oder ohne nachfolgende Wärmebehandlung sowie für kaltgeformte Hohlprofile mit einer anschließenden Wärmebehandlung oberhalb von 580 °C um gleichwertige mechanische Eigenschaften wie bei den warmgeformten Erzeugnissen zu erzielen.
ANMERKUNG 1 Die Anforderungen an die Grenzabmaße, Maße und statischen Werte sind in EN 10210-2 festgelegt.
ANMERKUNG 2 Der Anwender wird darauf aufmerksam gemacht, dass die kaltgeformten Hohlprofile nach EN 10219-3 zwar vergleichbare mechanische Eigenschaften zu den warmgefertigten Hohlprofilen nach EN 10210-3 aufweisen können, dass aber die Maße und statischen Werte von quadratischen und rechteckigen Hohlprofilen nach EN 10210-2 und EN 10219-2 nicht vergleichbar sind.
ANMERKUNG 3 Eine Anzahl von Stahlsorten ist in dieser Norm festgelegt und der Anwender kann die geeignetste Sorte für die beabsichtigte Verwendung aussuchen. Die Sorten und die mechanischen Eigenschaften der fertigen Hohlprofile sind im Allgemeinen vergleichbar mit den Sorten die in EN 10025-4, EN 10025-5 und EN 10025-6 aufgeführt sind.  
ANMERKUNG 4 Nahtlose und geschweißte Hohlprofile für Offshore-Konstruktionen werden in der Europäischen Normenserie EN 10225 behandelt.
ANMERKUNG 5 Es wird erwartet, dass spiralnahtgeschweißte Hohlprofile mit Vorsicht bei Anwendungen, die dynamische Beanspruchung (Ermüdungsbelastung) einschließen, verwendet werden, da es bis heute nur unzureichende Daten bezüglich des Verhaltens gibt.

Profils creux de construction finis à chaud en aciers - Partie 3 : Conditions techniques de livraison des aciers à haute limite élastique et des aciers à résistance améliorée à la corrosion atmosphérique

Le présent document spécifie les conditions techniques de livraison pour les profils creux de construction finis à chaud des aciers à haute limite élastique et des aciers à résistance améliorée à la corrosion atmosphérique sans soudure, soudés électriquement et soudés à l’arc immergé de forme circulaire, carrée, rectangulaire ou elliptique.
Il s’applique aux profils creux formés à chaud, avec ou sans traitement thermique ultérieur, ou formés à froid avec traitement thermique ultérieur supérieur à 580 °C afin d’obtenir des caractéristiques mécaniques équivalentes à celles des produits formés à chaud.
NOTE 1   Les exigences pour les tolérances, dimensions et caractéristiques de section sont spécifiées dans l’EN 10210-2.
NOTE 2   L’attention des utilisateurs est attirée sur le fait que, même si les nuances formées à froid de l' EN 10219-3 peuvent avoir des caractéristiques mécaniques équivalentes aux nuances finies à chaud du présent document, les caractéristiques de section des profils creux carrés et rectangulaires de l’EN 10210-2 et de l’EN 10219-2 ne sont pas équivalentes.
NOTE 3   Une gamme de nuances de matériau est spécifiée dans le présent document, et l’utilisateur peut sélectionner la nuance la plus appropriée à l’utilisation et aux conditions de service prévues. Les nuances et caractéristiques mécaniques des profils creux finis sont généralement comparables à celles de l’EN 10025-4, l’EN 10025-5 et l’EN 10025-6.
NOTE 4   Les exigences pour les profils creux de construction en aciers sans soudure et soudés destinés aux structures marines sont couvertes par la série des EN 10225.
NOTE 5   Les profils creux soudés en spirale doivent être utilisés avec prudence dans les applications impliquant un comportement dynamique (contrainte en fatigue) important car jusqu'à présent, les données concernant leurs performances sont insuffisantes.

circular, square, rectangular or elliptical forms.
It applies to hollow sections formed hot, with or without subsequent heat treatment, or formed cold
with subsequent heat treatment above 580 °C to obtain equivalent mechanical properties to those
obtained in the hot formed product.
NOTE 1 The requirements for tolerances, dimensions and sectional properties are specified in EN 10210-2.
