Full Description
ISO 21028-2:2018 specifies the toughness requirements of metallic materials for use at temperatures between 20 C and 80 C to ensure their suitability for cryogenic vessels. This document is applicable to 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.
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.
