(Main)Steel forgings for pressure purposes - Part 2: Ferritic and martensitic steels with specified elevated temperatures properties
Steel forgings for pressure purposes - Part 2: Ferritic and martensitic steels with specified elevated temperatures properties
This part of this European Standard specifies the technical delivery conditions for forgings for pressure purposes, made of ferritic and martensitic steels with specified elevated temperature properties. 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 condition is given in EN 10021.
Schmiedestücke aus Stahl für Druckbehälter - Teil 2: Ferritische und martensitische Stähle mit festgelegten Eigenschaften bei erhöhten Temperaturen
Dieser Teil dieser Europäischen Norm legt die technischen Lieferbedingungen für Schmiedestücke für Druckbehälter aus ferritischen und martensitischen Stählen für den Einsatz mit festgelegten Eigenschaftenbei erhöhten Temperaturen 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 ermittelt 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 2 : Aciers ferritiques et martensitiques avec propriétés spécifiées à température élevée
La présente partie de la norme européenne spécifie les conditions techniques de livraison des pièces forgées en aciers ferritiques et martensitiques, avec caractéristiques spécifiées à température élevée, pour appareils à pression. Les compositions chimiques et les propriétés mécaniques sont spécifiées.
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.

1 Scope
This part of this European Standard specifies the technical delivery conditions for forgings for pressure
purposes, made of ferritic and martensitic steels with specified elevated temperature properties.
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 condition is given in EN 10021.

a
Elements not listed in this table shall not be intentionally added to the steel without the approval of the purchase except for finishing the cast. All appropriate measures shall be taken to prevent the
addition from scrap or other materials used in steelmaking of these elements which may have adversely affect the mechanical properties and usability.
b
If resistance to pressurized hydrogen is of importance, a min. content of Cr of 0,80 % may be agreed at the time of enquiry and order.

If several product analyses are carried out for one cast and if, in this case,
values for individual elements are established which fall outside the permitted
range for the chemical composition, then it is only permissible that the values
either exceed the maximum permitted value or fall short of the minimum
permitted value. It is not acceptable for both to apply for one cast.

a
The thickness ranges given in this column apply for the as heat treated thickness of forgings with the ruling
section. This is characterized by rectangular shape, a width to thickness ratio of ≥ 2 and a length to thickness ratio
of ≥ 4. For forgings with other sections the equivalent thickness shall be determined according to
EN 10222-1:2017, Annex A or be agreed at the time of enquiry and order.
b
Until the yield point criteria are harmonized in the various national codes, determination of ReH may be replaced
by determination of R . In this case R values are 10 MPa lower for R values up to 355 MPa and 15 MPa

lower for ReH values greater than 355 MPa.
