EN ISO 21028-2:2018 Cryogenic vessels - Toughness requirements for materials at cryogenic temperature - Part 2: Temperatures between -80 degrees C and -20 degrees C
This document specifies the toughness requirements of metallic materials for use at temperatures between ?20 ??and ?80 ??to ensure their suitability for cryogenic vessels. This document is applicable to fine-grain and low-alloyed steels with specified yield strength ??60 N/mm2@ aluminium and aluminium alloys@ copper and copper alloys and austenitic stainless steels. NOTE For steel materials listed in EN 13445-2 or EN 13480-2 or for steel materials and weldings complying with the same fundamental safety requirements@ the requirements for prevention of brittle fracture at low temperatures according to EN 13445-2:2014@ Annex B@ method 2@ or EN 13480-2:2012@ Annex B@ method 2 can be applied.
