Application/
Properties:
Fully austenitic
stainless steels
welding rod for
TIG welding of
heat resistant
steels,
containing 25%
Cr and 20% Ni.
Likewise suited
for welding heat
and scaling
resistant
ferritic
chromium steels
unless corrosion
attack by
reducing sulphur-bearing
combustion gases
is to be
expected.
Non-scaling up
to 1200 ˚C. Weld
metal exhibits
good toughness
down to -196 ˚C. |
