Exaton 308/308L (CRYO)

308/308L (CRYO) is a filler material for joining austenitic stainless steels, e.g. ASTM 304, 304L (18Cr/8Ni/ELC), for cryogenic applications and meets the requirements of ASME Section VIII, Division 1, UHA 51 ((a) (4) (-a) (-1)) and others. It is also used for service temperatures down to -269°C (-452°F), and ferritic or martensitic stainless steels with maximum 19% Cr. 308/308L (CRYO) is approved by TÜV Rheinland for use at cryogenic temperatures down to 4K (-269°C (-452°F). It is suitable for joining stainless steels of 18Cr/8Ni/Nb types, e.g. ASTM 347, for service temperatures up to 350°C (660°F). It is used for MIG/MAG welding. Specifically developed for welding in cryogenic applications, typically: manufacturing of dewars, containers, tanks, cryostats, and transfer systems for transportation and storage of LNG, LPG, liquid nitrogen and liquid helium. The chemical composition is optimized for cryogenic applications in terms of impact strength and other characteristics. It has a controlled chemical composition and ferrite content for resistance to microfissuring, and balanced minor additions of certain elements for optimum arc stability, fluidity and low spatter.
