UTP 6809 Mo
Rutil-basic coated austenitic-ferritic
stick electrode with low C-content
Application field
UTP 6809 Mo is a rutile basic coated stick electrode forjoining and surfacing on corrosion resistant steels
and cast steels with an austenitic-ferritic structure (Duplex-steels).
Base materials
1.4460, 1.4462
Welding properties
UTP 6809 Mo is weldable in all positions except vertical-down. Stable arc, very good slag removal, finely
rippled and a notch free weld seam. The deposit is especially resistant to pitting, gap- and stress corrosion
cracking in chloride containing media (e.g. seawater)
