Description
Rutile electrode, designed for ferritic-austenitic duplex steels, Field of applications are in
off-shore engineering and in the chemical industry. high mechanical strength and
toughness, the weld metal is also noted for excellent resistance to stress corrosion
cracking and pitting resistance. excellent positional weldability. the good wetting
characteristics, slag removability, resistance to porosity with a fully alloyed core wire
providing best corrosion resistance and a very homogeneous micro structure with
specified ferrite contents of 30 – 60 FN.
