Fracture Properties of a 25Mn Austenitic Steel and its Welds At 4 K
Chapter
Abstract
A low-carbon, 25Mn-5Cr-lNi, austenitic steel has been developed for cryogenic applications. Previous work indicated that the 25Mn steel has excellent strength and ductility to 4 K,1 high Charpy impact toughness to 23 K (the minimum temperature tested),1,2 a stable austenite microstructure,1,2 and a low (relative to stainless steels) thermal expansion coefficient.3 A weld metal with nearly matching composition, 25Cr-2.8Ni-6.SCr-l.4Mo, has comparable properties.
