Application /
Properties:Basic
Electrode for joining of
dissimilar steels,
(austenitic steels to
ferritic steels) and for
depositing claddings
austenitic. weld metal
consists of with
approximately 15%
delta-ferrite. claddings on
alloyed or low-alloyed steel
are already corrosion
resistant in the first
layer. highest operating
temperature for dissimilar
steel joints is +300 C, at
higher temperature 1604 G
electrode shall be used.
