Characteristics and field of use
Core wire alloyed, rutile coated stick electrode for welding ferritic-austenitic duplex steels such as
1.4462, UNS 31803. Used primarily in the fields of offshore engineering and chemical industry.
In addition to increased strength and toughness, the weld metal has an exceptional resistance to
stress corrosion cracking due to the high proportion of ferrite. Good pitting resistance according to
ASTM G48 / method A. The 2.0 and 2.5 mm dimensions when used at the DC negative pole are
particularly suitable for vertical up welding of pipes in the root and in the subsequent passes, which
is necessary, for instance, in oilfield engineering. Good AC weldability. All dimensions suitable for
position welding.
