UTP A6222 MO TIG Wire (625)
Specifications
UTP A 6222 Mo has a high nickel content and is suitable for welding high-strength and highcorrosion resistant nickel-base alloys.
It can be used for joining ferritic steel to austenitic steel as well as for surfacing on steel. It is also
possible to weld 9 % nickel steels using this wire due to its high yield strength. Its wide range of
uses is of particular signifiance in aviation, in chemical industry and in applications involving
seawater.
The special features of the weld metal of UTP A 6222 Mo include a good creep rupture strength,
corrosion resistance, resistance to stress and hot cracking. It is highly resistant and tough even at
working temperatures up to 1100° C. It has an extremely good fatigue resistance due to the
alloying elements Mo and Nb in the NiCr-matrix. The weld metal is highly resistant to oxidation and
is almost immune to stress corrosion cracking. It resists intergranular penetration without having
been heat-treated.
