High Strength/Cryogenic Filler Metals – GMAW Solid Wires
BÖHLER 2.5 Ni-IG
GMAW solid wires, low-alloyed,
cryogenic application
Description
2.5 % Ni-alloyed GMAW wire for high quality welds in the construction of storage tanks and
piping systems for cryogenic applications. The weld deposit is noted for its particularly good low
temperature an non-ageing properties down to -80 °C.
