Cryogenic vessels - Materials - Part 2: Toughness requirements for temperatures between -80°C and -20°C
This European Standard specifies the toughness requirements of the metallic materials for use at a temperature between - 80 °C and - 20 °C ensuring suitability for use for the cryogenic vessels.
Fine grain and low alloyed steels with specified yield strength <= 460 N/mm², aluminium and aluminium alloys, copper and copper alloys and austenitic stainless steels are covered by this standard.
Kryo-Behälter - Werkstoffe - Teil 2: Anforderungen an die Fähigkeit bei Temperaturen zwischen -80°C und -20°C
1 Anwendungsbereich
Diese Europäische Norm legt Anforderungen an die Zähigkeit von Werkstoffen fest, die bei Temperaturen zwischen - 80 °C und - 20 °C verwendet werden, um deren Eignung für den Einsatz für Kryo - Behälter sicherzustellen.
Diese Norm gilt für Feinkornstähle und niedrig legierte Stähle mit festgelegter Streckgrenze £ 460 N/mm², Aluminium und Aluminiumlegierungen, Kupfer und Kupferlegierungen und austenitische nichtrostende Stähle.
Récipients cryogéniques - Matériaux - Partie 2: Exigences de ténacité pour les températures entre - 80°C et - 20°C
Domaine d'application
La présente Norme européenne spécifie les exigences de ténacité des matériaux métalliques utilisables à une température comprise entre - 80 °C et - 20 °C et, pour assurer leur aptitude à l'emploi pour les récipients cryogéniques.
Les aciers à grains fins et les aciers faiblement alliés avec une limite apparente d'élasticité * 460 N/mm2, les aluminium et alliages d'aluminium, les cuivres et alliages de cuivre et les aciers austénitiques inoxydables sont couverts par la présente norme.
