Steel forgings for pressure purposes - Part 5: Martensitic, austenitic and austenitic-ferritic stainless steels

This European Standard specifies the technical delivery conditions for forgings for pressure purposes, made of stainless steels, including creep resisting steels. Chemical composition and mechanical properties are specified.
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.

DDiese Europäische Norm legt die technischen Lieferbedingungen für Schmiedestücke für Druckbehälter aus nichtrostenden und aus hochwarmfesten Stählen fest. Die chemische Zusammensetzung und mechanische Eigenschaften sind festgelegt.
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 Informationen zu technischen Lieferbedingungen sind in EN 10021 enthalten.

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 10222-5:2017 - Steel forgings for pressure purposes (Part 5) defines the technical delivery conditions for stainless-steel forgings used in pressure equipment. It covers martensitic, austenitic and austenitic‑ferritic (duplex) stainless steels, including creep‑resisting grades. The standard specifies required chemical composition, mechanical properties, heat treatment regimes and testing/inspection obligations for forgings intended for pressure purposes.

Key topics and requirements

• Scope: Applies to forgings for pressure equipment made from specified stainless steel grades; chemical and mechanical data are given in tables within the standard.
• Steel classification & designation: Grades are grouped by microstructure - martensitic, austenitic and austenitic‑ferritic - and referenced to EN 10088‑1 steel numbers and names (examples in Table 1 and 2).
• Heat treatment and delivery condition: Solution annealing, tempering and quenching/tempering requirements are listed per grade (Table 1). Cooling media (air, oil, water) and special tempering notes are provided.
• Chemical composition: Cast analysis and allowable product analysis deviations are defined (Tables 2 & 3). Some grades include controlled elements (e.g., Ti, Nb, N) and optional controlled sulphur.
• Mechanical properties and elevated‑temperature data: Tensile, proof strength (including elevated‑temperature tests) and optional impact testing requirements are specified; reference creep data are provided in Annex A.
• Corrosion testing: Resistance to intergranular corrosion for austenitic and duplex steels is addressed with reference to EN ISO 3651‑2.
• Inspection, sampling, tests and marking: Procedures are aligned with EN 10222‑1 general requirements; test methods, retests, sampling and marking rules are included.
• Post‑weld heat treatment (PWHT): Guidance for PWHT is given in Annex B.
• Compliance note: When published in the OJEU under Directive 2014/68/EU, the standard offers presumption of conformity only to the material technical data; designers must verify material suitability for the specific equipment to meet Essential Safety Requirements.

Practical applications

• Specification and procurement of stainless steel forgings for boilers, pressure vessels, heat exchangers, valves and high‑temperature pressure parts.
• Material selection and quality acceptance for components requiring corrosion resistance, elevated‑temperature strength, or creep resistance.
• Basis for manufacturer delivery documentation, factory inspection and testing regimes.

Who uses this standard

• Pressure equipment manufacturers and fabricators
• Metallurgists and materials engineers
• Procurement/specification engineers in oil & gas, power generation, chemical and petrochemical industries
• Notified bodies and conformity assessment teams referencing Directive 2014/68/EU
