Rutil-acid-coated 29Cr9Ni welding electrode for welding austenitic ferrite (duplex) corrosion-resistant steels. Excellent for welding steels, mixed joints and steel castings of unknown composition.
Advantages:
It
can also be used to apply surfaces of less hardness (welded seam
hardness: 220-240 HV) such as gear teeth, cold forming tools and high
carbon steel tool steels as well as rails, rollers, forks, hot forming
and plastic press tools as pillow layers. The seam
is additionally resistant to stress corrosion, highly insensitive to
the effects of mixing with the raw material and resistant to
temperatures up to 1150 ° C.
