Steel forgings for pressure purposes - Part 3: Nickel steels with specified low temperature properties

This European Standard specifies the technical delivery conditions of forgings for pressure purposes, made of nickel steels, for use at low temperatures.
NOTE   Once this standard is published in the EU Official Journal (OJEU) under Directive 2014/68/EU, presumption of conformity to the Essential Safety Requirements (ESRs) of Directive 2014/68/EU is limited to technical data of materials in this standard 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 2014/68/EU are satisfied, needs to be done. The series EN 10222-1 to EN 10222-5 is structured so that the data related to different materials is in the part allocated for that material. The presumption of conformity to the Essential Safety Requirements of Directive 2014/68/EU depends on both the text in part 1 and the data in part 2, 3, 4 or 5.
General information on technical delivery conditions is given in EN 10021.

Schmiedestücke aus Stahl für Druckbehälter - Teil 3: Nickelstähle mit festgelegten Eigenschaften bei tiefen Temperaturen

Diese Europäische Norm legt die technischen Lieferbedingungen an Schmiedestücke für Druckbehälter aus Nickelstählen für den Einsatz bei niedrigen Temperaturen fest.
ANMERKUNG   Nach Veröffentlichung dieser Norm im Amtsblatt der Europäischen Union (ABl.) unter der Richtlinie 2014/68/EU beschränkt sich die Vermutung der Konformität mit den grundlegenden Sicherheitsanforderungen (ESR, en: essential safety requirements) der Richtlinie 2014/68/EU auf die technischen Daten von Werkstoffen in dieser Norm. Eine Vermutung der Eignung des Werkstoffs für ein bestimmtes Ausrüstungsteil wird nicht gegeben. Folglich müssen die in dieser Werkstoffnorm angegebenen technischen Parameter im Hinblick auf die konstruktiven Anforderungen dieses bestimmten Ausrüstungsteils beurteilt werden, um damit zu verifizieren, dass den ESR der Richtlinie 2014/68/EU entsprochen wird. Die Reihe EN 10222-1 bis -5 ist so aufgeteilt, dass die Daten von verschiedenen Werkstoffen in dem entsprechenden Teil zu finden sind. Die Vermutung der Konformität mit den grundlegenden Sicherheitsanforderungen der EU-Richtlinie 2014/68/EU hängt sowohl vom Text in Teil 1 als auch von den Daten in den Teilen 2, 3, 4 oder 5 ab.
Allgemeine Angaben zu technischen Lieferbedingungen sind in EN 10021 enthalten.

Pièces forgées en acier pour appareils à pression - Partie 3: Aciers au nickel avec caractéristiques spécifiées à basse température

La présente partie de la norme européenne spécifie les conditions techniques de livraison des pièces forgées en aciers au nickel pour appareils à pression utilisés à basse température.
NOTE   Dès lors que la présente Norme européenne est citée dans le Journal Officiel de l’Union européenne (JOUE) en lien avec la Directive 2014/68/UE, la présomption de conformité avec les exigences essentielles de sécurité de la Directive 2014/68/UE se limite aux données techniques relatives aux matériaux spécifiés dans la présente Norme européenne et ne suppose pas l’adéquation des matériaux avec un appareil en particulier. Par conséquent, il doit être procédé à l’évaluation des données techniques spécifiées dans la présente norme de matériaux par rapport aux exigences relatives à la conception de cet équipement spécifique, afin de vérifier que les exigences essentielles de sécurité de la Directive 2014/68/UE sont satisfaites. La série de normes 10222-1 à 10222-5 est structurée de telle façon que les données relatives aux différents matériaux sont dans la partie dédiée à ce matériau. La présomption de conformité aux exigences essentielles de sécurité de la Directive 2014/68/UE dépend à la fois du texte de la partie 1 et des données contenues dans les parties 2,3,4 ou 5.
Les informations générales sur les conditions techniques de livraison sont données dans l'EN 10021.

Overview

EN 10222-3:2017 - Steel forgings for pressure purposes, Part 3: Nickel steels with specified low temperature properties (CEN) specifies the technical delivery conditions for forgings intended for pressure equipment where low-temperature toughness is critical. The standard covers classification, designation, purchaser information, chemical composition, heat treatment, mechanical and impact properties, inspection, sampling and marking of nickel-alloyed steels used in pressure applications. It supports, but does not alone guarantee, conformity with the Essential Safety Requirements of EU Directive 2014/68/EU (see annex ZA).

Key topics and technical requirements

• Material scope and classification

  • Applies to specified nickel steel grades (e.g., 13MnNi6–3, 15NiMn6, 12Ni14, X12Ni5, X8Ni9) for pressure purposes.
  • Grades are treated as alloy special steels (see EN 10020 principles).

• Heat treatment and delivery condition

  • Heat-treatment regimes (normalized, normalized & tempered, quenched & tempered, and variants with minimum tensile strengths) are defined and linked to required mechanical and impact performance.

• Chemical composition and product analysis

  • Cast-analysis limits and permissible product-analysis deviations are given in tabulated form.
  • Limits on unintended elements (Cr, Cu, Mo totals) are specified to protect low-temperature properties.

• Mechanical properties

  • Minimum yield, tensile strength and elongation values at room temperature are specified by grade and ruling section thickness.
  • Equivalent thickness rules and determination of ruling sections reference EN 10222-1.

• Impact toughness at low temperatures

  • Detailed minimum Charpy impact energy values are provided for longitudinal and transverse specimens across specified test temperatures (down to cryogenic ranges for some grades).
  • Impact test temperature and direction must be agreed at enquiry/order when not fixed.

• Special tests and options

  • Optional test for resistance to hydrogen-induced cracking (sour service) per EN 10229 may be agreed.
  • Options include variations in nickel content and alternative minimum impact energy levels.

• Inspection, sampling, marking and test methods

  • Inspection, sampling, test methods, retests and marking requirements are referenced to EN 10222-1 and EN 10021 where appropriate.

Applications and users

• Typical users:
  • Pressure vessel and boiler manufacturers, forging producers, material engineers, QA/QC and procurement teams in oil & gas, LNG, cryogenics, chemical and petrochemical plants.
• Practical uses:
  • Specifying forged components (flanges, closures, nozzles, valve bodies) that must retain toughness at low or cryogenic temperatures.
  • Material selection for sour-service or low-temperature pressure equipment where documented mechanical and impact data are required.
