Designation systems for steels - Part 2: Numerical system
This European Standard sets out a numbering system, referred to as steel numbers, for the designation of steel grades. It deals with the structure of steel numbers and the organization for their registration, allocation and dissemination. Such steel numbers are complementary to steel names set out in EN 10027-1.
Application of this European Standard is obligatory for steels specified in European Standards. Application is optional for national steels and proprietary steels.
NOTE Although the scope of the systems is limited to steel, it is structured so as to be capable of being extended to include other industrially produced materials.
Steel numbers established according to this system have a fixed number of digits (see 5). They are better suited for data processing than steel names established according to EN 10027-1.
For steels specified in European Standards the application for allocation of steel numbers (see A.6 to A.9) is the responsibility of the ECISS Technical Committee concerned. For national steel grades, the responsibility is that of the national competent body.
Bezeichnungssysteme für Stähle - Teil 2: Nummernsystem
1.1 Diese Europäische Norm legt ein Nummernsystem für die Bezeichnung von Stahlsorten fest, das im Folgenden als Werkstoffnummernsystem bezeichnet wird. Sie behandelt den Aufbau, die Vergabe, die Registrierung und Bekanntmachung der Werkstoffnummern. Diese Werkstoffnummern gelten zusätzlich zu den Kurznamen nach EN 10027-1.
Die Anwendung dieser Europäischen Norm ist für alle in Europäischen Normen enthaltenen Stähle verbindlich. Auf Wunsch können Werkstoffnummern auch für nationale Stahlsorten einschließlich Werkssorten angewendet werden.
ANMERKUNG Obwohl der Anwendungsbereich des Systems auf Stahl begrenzt ist, ist Vorsorge für eine Erweiterung des Systems zwecks Berücksichtigung auch anderer industriell hergestellter Werkstoffe getroffen worden.
1.2 Die nach diesem Nummernsystem festgelegten Werkstoffnummern haben eine bestimmte Stellenzahl (siehe Abschnitt 5). Sie sind daher für die Datenverarbeitung besser geeignet als die nach EN 10027-1 gebildeten Kurznamen der Stähle.
1.3 Anträge auf die Vergabe von Werkstoffnummern (siehe A.6 bis A.9) sind zu stellen:
- für in Europäischen Normen enthaltene Stähle durch das zuständige Technische Komitee des ECISS;
- für nationale Stahlsorten durch die zuständige nationale Stelle.
ANMERKUNG Anträge europäischer Organisationen, die ein besonderes Interesse an der Normung von Stählen und Stahlerzeugnissen haben (z. B. ASD, EUROFER) können über das ECISS-Zentralsekretariat eingereicht werden (siehe A.9).
Systèmes de désignation des aciers - Partie 2: Système numérique
1.1 La présente norme européenne spécifie un système de numérotation pour la désignation des nuances d´aciers. Elle traite de la structure des numéros d´aciers ainsi que de l´organisation pour leur enregistrement, allocation et diffusion. Ce système est dénommé système numérique. Les numéros d´aciers correspondants sont complémentaires des désignations symboliques, décrites dans la partie 1 de l´EN 10027.
Cette présente norme européenne s‘applique pour les nuances d´aciers définies dans les normes européennes. Elle peut également être employée pour les nuances d´aciers nationales et les aciers de marque.
NOTE Bien que l´objet du système soit limité à l´acier, il est structuré de façon à pouvoir être étendu pour inclure d´autres produits fabriqués industriellement.
1.2 Les numéros d´aciers établis conformément à ce système ont un nombre fixe de chiffres (voir article 5). Ils sont en conséquence mieux adaptés pour le traitement de données que les noms des aciers établis selon la partie 1 de la norme EN 10027.
1.3 Pour les nuances d´aciers définies dans les normes européennes, la présentation de la demande d´attribution des numéros d´aciers (voir A.6 à A.9) relève de la responsabilité du Comité Technique concerné de l’ECISS. Pour les nuances d´aciers nationales la même responsabilité incombe à l´organisme national compétent.
NOTE Les demandes provenant d´organisations actives sur le plan européen et ayant un intérêt spécifique dans la normalisation de l´acier, et des produits en acier (telles que, par exemple, l´ASD, EUROFER, etc.) doivent alors être soumises via le Secrétariat Central de l´ECISS (voir A.9).

Overview
EN 10027-2:2015 - Designation systems for steels - Part 2: Numerical system - defines a standardized numerical designation (steel numbers) for steel grades used across Europe. Published by CEN, it specifies the structure, registration, allocation and dissemination procedures for steel numbers that complement the steel names defined in EN 10027-1. Application is obligatory for steels specified in European Standards and optional for national or proprietary steels.
Key topics
- Purpose and principles
- One-to-one mapping: each steel number refers to a single steel grade and vice versa.
- Steel numbers are stable (not normally changed) and better suited for data processing than text-based steel names.
- Structure of steel numbers
- Fixed number of digits organized into: material group number, steel group number (see Table 1 in the standard), and a sequential number.
- Recent revision extended the sequential number to four digits with rules for orderly allocation.
- Registration and allocation
- Allocation requests are submitted using Form I (chemical criteria) or Form II (mechanical criteria) per Annex B.
- The appointed European Registration Office (Stahlinstitut VDEh – Europäische Stahlregistratur, www.stahldaten.de) administers the registry and publishes registered steels.
- For European-standard steels allocation responsibility lies with the relevant ECISS Technical Committee; for national steels, the national competent body handles allocation.
- Management rules
- Deleted steel numbers are retained in records and must not be re-allocated.
- Allocation is based on significant differences in material characteristics (chemical composition, mechanical properties, processing suitability, application-specific traits).
Applications
EN 10027-2:2015 is practical for:
- Manufacturers, standard writers and registrars who need consistent, machine-readable steel grade identifiers.
- ERP, PLM and materials databases that require unambiguous numeric keys for steels for procurement, traceability and quality control.
- Test labs and certification bodies issuing reports that reference standardized steel numbers.
- National standards bodies and industry committees managing steel specifications and cross-references.
Who uses this standard
- Steel producers and mills
- Standards committees (ECISS)
- National competent bodies for steel registration
- Engineers, purchasers and database administrators involved in materials identification and data exchange
