Flat products made of steels for pressure purposes - Part 6: Weldable fine grain steels, quenched and tempered
This European Standard specifies the requirements for flat products for pressure equipments made of quenched
and tempered steels as specified in Table 1.
The requirements in EN 10028-1 also apply.
NOTE Once this European Standard is published in the EU Official Journal (OJEU) under Directive 97/23/EC, presumption of
conformity to the Essential Safety Requirements (ESRs) of Directive 97/23/EC is limited to technical data of materials in this
European Standard (Part 1 and this Part 6 of the series) and does not presume adequacy of the material to a specific item of
equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements
of this specific item of equipment to verify that the ESRs of Directive 97/23/EC are satisfied, needs to be done.
Flacherzeugnisse aus Druckbehälterstählen - Teil 6: Schweißgeeignete Feinkornbaustähle, vergütet
In dieser Europäischen Norm sind die Anforderungen an Flacherzeugnisse für Druckbehälter aus den
thermomechanisch gewalzten Stählen nach Tabelle 1 festgelegt.
Diese Stähle sind nicht für die Warmumformung geeignet.
ANMERKUNG 1 Zum Zeitpunkt der Veröffentlichung dieser Europäischen Norm standen für die Normung der
Eigenschaften dieser Stähle bei erhöhter Temperatur keine hinreichende Angaben zur Verfügung. Sollte ihr Einsatz bei
diesen Temperaturen beabsichtigt sein, so sollten die Bedingungen dafür zwischen den interessierten Parteien vereinbart
werden.
Zusätzlich gelten die Anforderungen in EN 10028-1:2007+A1:2009.
ANMERKUNG 2 Nach Veröffentlichung dieser Norm im EU-Amtsblatt (OJEU) unter der Richtlinie 97/23/EC ist die
Annahme ihrer Konformität mit den grundlegenden Anforderungen (ESR) der Richtlinie 97/23/EC auf die technischen
Daten von Werkstoffen in dieser Europäischen Norm (Teil 1 und dieser Teil 5 der Normenreihe) beschränkt, und es darf
nicht angenommen werden, dass damit die Eignung des Werkstoffs für ein bestimmtes Ausrüstungsteil festgestellt ist.
Folglich müssen die in dieser Werkstoffnorm angegebenen technischen Parameter im Hinblick auf die konstruktiven
Anforderungen dieses bestimmten Ausrüstungsteils ermittelt werden, um damit zu verifizieren, dass den ESR der
Richtlinie 97/23/EC entsprochen wird.
Produits plats en acier pour appareils à pression - Partie 6: Aciers soudables à grains fins, trempés et revenus
La présente Norme européenne spécifie les prescriptions relatives aux produits plats pour appareils à pression en
aciers trempés et revenus, telles que spécifiées dans le Tableau 1.
Les prescriptions et définitions de l’EN 10028-1:2007 + A1:2009 s’appliquent également.
NOTE Après publication de la présente Norme européenne dans le Journal Officiel de l'UE (OJEU) sous la Directive
97/23/EC, la présomption de conformité aux Exigences Essentielles de Sécurité (ESRs) de la Directive 97/23/EC se limite aux
données techniques des matériaux de la présente Norme européenne (Partie 1 et la présente Partie 6 de la série) et ne
suppose pas l'adéquation du matériau à un élément ou à un équipement spécifique. En conséquence, l'évaluation des données
techniques énoncées dans la présente norme de matériau en fonction des exigences de conception de cet élément spécifique
d'équipement pour vérifier que les ESR de la Directive 97/23/EC sont respectées, doit être effectuée.

b) series with elevated temperature properties (P.QH); c) series with low temperature properties down to -40 °C (P.QL1); d) series with low temperature properties down to -60 °C (P.QL2). 6.1.2 In accordance with EN 10020 all the steels specified in this document are alloy special steels. 6.2 Designation See EN 10028-1:2007 + A1:2009. SIST EN 10028-6:2009
EN 10028-1:2007 + A1:2009 apply. If the purchaser does not indicate a wish to implement any of these options at the time of enquiry and order, the products shall be supplied in accordance with the basic specification (see also
EN 10028-1:2007 + A1:2009). 1) providing data on suitable welding conditions (see 8.2.3); 2) mid thickness test pieces for the impact test (see Clause 10); 3) lower copper content and maximum tin content (see Table 1, footnote c); 4) mechanical properties for thicknesses > 150 mm (see Table 3, footnote b); 5) specification of a minimum impact energy of 40 J (see Note to 8.4 and Table 4, footnote a); 6) applicability of elevated temperature values for QL grades (see Table 5, footnote b). 7.3 Example for ordering 10 plates with nominal dimensions, thickness = 50 mm, width = 2 000 mm, length = 10 000 mm, made of a steel grade with the name P355QL2 and the number 1.8869 as specified in EN 10028-6, inspection certificate 3.1 as specified in EN 10204: 10 plates – 50 x 2 000 x 10 000 – EN 10028-6 P355QL2 – Inspection certificate 3.1 or 10 plates – 50 x 2 000 x 10 000 – EN 10028-6 1.8869 – Inspection certificate 3.1. 8 Requirements 8.1 Steelmaking process See EN 10028-1:2007 + A1:2009. 8.2 Delivery condition 8.2.1 The products covered by this European Standard shall be supplied in the quenched and tempered condition. 8.2.2 The steels specified in this European Standard shall be suitable for welding processes in current use (see Notes 1 to 3 to 8.2.3). 8.2.3 •• The manufacturer shall, if requested, provide the purchaser with data on suitable welding conditions determined on the basis of weld procedure tests. NOTE 1
With increasing product thickness and strength level cold cracking can occur. Cold cracking is caused by the follo-wing factors in combination: a)
the amount of diffusible hydrogen in the weld metal; b)
brittle structure of the heat affected zone; SIST EN 10028-6:2009
tensile stress concentrations in the welded joint. NOTE 2
When using recommendations as laid down, for example in EN 1011-1 and EN 1011-2, the recommended welding conditions and the various welding ranges of the steel grades can be determined depending on the product thickness, the applied welding energy, the design requirements, the electrode efficiency, the welding process and the weld metal properties. NOTE 3 Excessive post weld heat-treatment (PWHT) conditions can decrease the mechanical properties. It is therefore recommended that the purchaser seeks, at the time of enquiry and order, the advise of the manufacturer and considers, where appropriate, the verification of the mechanical properties on simulated post weld heat treated samples. 8.3 Chemical composition 8.3.1 The requirements of Table 1 apply for the chemical composition according to the cast analysis. 8.3.2 The product analysis may deviate from the specified values of the cast analysis given in Table 1 by the values given in Table 2. 8.4 Mechanical properties The values given in Tables 3 to 5 apply (see also EN 10028-1:2007 + A1:2009 and Clause 10).
