Characteristics and field of use
UTP 2205 is a Cr-Ni-Mo alloyed duplex electrode for welding duplex steels such as 2205.
For light to moderate thickness material, welding should be carried out as for ordinary
austenitic stainless steel. However, the somewhat lower penetration and fluidity of the weld
should be considered. Very high quench rates and excessive times at red heat or above
should be avoided to prevent excessive ferrite or bation of interbllic phases.
Interpass temp.: Max. 150 °C.
Heat b: 0,5 – 2,5 kJ/mm.
Heat treatment: Generally none
(in special cases quench annealing at 1100 – 1150 °C).
Structure: Austenite with approx. 30 % ferrite.
Scaling temperature: Approx. 850 °C (air).
Corrosion resistance: Very good resistance to pitting and stress corrosion cracking in
chloride containing environments.
Weld deposit data: Metal recovery approx. 110 %.
