UTP A 2522 Mo
Fully austenitic welding welding wire
for high corrosion resistant steels.
Application field
UTP A 2522 Mo is suitable for joinings and surfacings on corrosion resistant CrNiMo-steels. Main application
fields are hard stressed steels, urea- and nitric acid plants as for example material-no. 1.4465
(X 2CrNiMoN 25 25) and other corrosion resistant steels with a fully austenitic structure.
Properties of the weld metal
Due to the special chemical composition UTP A 2522 Mo is hot crack resistant and highly resistant to
intercristalline corrosion. Besides it is resistant to oxidizing and reducing media due to the high chromium
and nickel contents.
