Steel closed die forgings - General technical delivery conditions
This European Standard specifies the general delivery conditions for steel closed die forgings. These forgings are produced by blow or pressure of the heated product at a suitable temperature (hot or warm) in a die, which in the forming process shapes the material to the form of the die. Similar products such as warm extrusions and upset forgings, are also regarded as part of the process.
Gesenkschmiedeteile aus Stahl - Allgemeine technische Lieferbedingungen
Diese Europäische Norm legt die allgemeinen Lieferbedingungen für Gesenkschmiedeteile aus Stahl fest. Diese Schmiedeteile werden durch Schlag oder Druck bei einer angemessenen Temperatur (warm oder halbwarm) in einem Gesenk hergestellt, das während des Umformprozesses das Vormaterial entsprechend seiner Hohlform ausbildet. Änhliche Teile, wie Warmfließpreß- und Stauchteile werden ebenfalls als Teil des Herstellungsprozesses gesehen.
Pièces estampées en acier - Conditions techniques générales de livraison
La présente Norme européenne spécifie les conditions générales de livraison des pièces estampées en acier. Les pièces estampées sont produites par frappe ou compression du produit chauffé à une température appropriée (chaude ou très chaude) dans une matrice ce qui, dans le processus de formage, fait prendre au matériau la forme de la matrice. Les produits similaires telles que les pièces extrudées à chaud et les pièces refoulées sont également considérés comme faisant partie du procédé.

Overview
EN 10254:1999 - Steel closed die forgings - General technical delivery conditions is a European (CEN) standard that specifies the general delivery conditions for steel closed die forgings. The standard covers forgings produced by blow or pressure of a heated product at a suitable temperature (hot or warm) in a die. It also regards similar processes such as warm extrusions and upset forgings as part of the forging process. The Slovenian adoption of this standard is published as SIST EN 10254:2000.
Key topics
EN 10254:1999 addresses the core contractual and technical elements that govern the supply of steel closed die forgings. While the standard text sets the authoritative requirements, typical topics covered include:
- Scope and definitions - clarifies what constitutes closed die forgings, warm extrusions, and upset forgings.
- General delivery conditions - the contractual framework between purchaser and supplier for forged parts.
- Manufacturing process description - identification of hot and warm forging processes used to form the material in a die.
- Material and product identification - how forgings are identified and documented through production and delivery.
- Dimensional and geometric considerations - expectations for conformity with specified sizes and shapes.
- Surface condition and finish - acceptable surface state on delivery and handling of defects.
- Heat treatment and thermal processing - provisions for delivered condition (hot/warm) and any specified thermal operations.
- Inspection, testing and documentation - requirements for inspection, test records, certificates and acceptance criteria.
- Marking, packaging and transport - instructions to ensure safe, traceable delivery.
(Note: the standard text provides the definitive requirements; the above topics summarize areas typically covered under general delivery conditions.)
Applications
EN 10254:1999 is used to define clear, consistent delivery requirements for suppliers and purchasers of forged steel components. Practical uses include:
- Preparing purchase specifications and contracts for steel closed die forgings.
- Guiding quality assurance and inspection plans at forging suppliers.
- Ensuring traceability and conformity during procurement and acceptance.
- Reducing disputes by specifying delivery, marking, documentation and packaging expectations.
Typical users: forging manufacturers, component suppliers, procurement teams, quality managers, design and mechanical engineers who specify forged parts.
