W 22 9 3 N L ER 2209 ~ 1.4462
Characteristics and field of use
UTP A 6808 Mo is used for joining and surfacing of corrosion resistant steels as well as
cast steel with austenitic-ferritic structure (Duplex steel). Working temperature:
up to 250 °C
The weld deposit of UTP A 6808 Mo has an excellence resistance against pitting and stress
corrosion cracking next to high strength- and toughness-properties. Very good weld- and
flow characteristics.
