Die meisten Stähle, die in diesem Dokument aufgeführt sind, sind mit jenen identisch, die in EN ISO 683- 1 und EN ISO 683- 2 festgelegt sind. Umfassendere Angaben über die Härtbarkeit und technologische Eigenschaften werden in diesen Normen getroffen.
Angaben über die allgemeinen technischen Lieferbedingungen enthält EN 10021.
Pièces forgées en acier pour usage général - Partie 3: Aciers spéciaux alliés
Le présent document spécifie les exigences techniques générales de livraison des pièces obtenues par forgeage libre, des barres forgées et des produits pré-forgés et finis par laminage circulaire, fabriqués en aciers spéciaux alliés et livrées à l'état trempé et revenu.
La majorité des aciers cités dans le présent document sont identiques aux aciers spécifiés dans l’EN ISO 683-1 et l’EN ISO 683-2, et des informations plus complètes sur la trempabilité et les propriétés technologiques sont données dans ces normes.
Les informations générales sur les conditions techniques de livraison sont données dans l’EN 10021.
Prosto kovani jekleni izkovki za splošno tehnično uporabo - 3. del: Legirana plemenita jekla
Ta del tega evropskega standarda določa tehnične dobavne zahteve za prosto kovane izkovke, kovane drogove in izdelke, predhodno kovane in dokončane v mlinih z obročastimi valji, ki so izdelani iz legiranega plemenitega jekla ter dobavljeni v kaljenem in tempranem stanju. Opomba: Večina jekel, navedenih v tem delu standarda EN 10250, je enaka jeklom iz standarda EN 10083-1, v tem evropskem standardu pa so podane obsežnejše informacije o kaljivosti in tehnoloških lastnostih.
