Product information

Unitor Iduplex-222 is a TIG rod for welding duplex stainless steel grades like WNr.1.4462, UNS 31803. The deposit offers elevated mechanical strength and toughness resistance to stress corrosion cracking. Application areas are similar to those for coated electrode Duplex-325 N, but with the advantages TIG can offer.


  • High mechanical strength and toughness
  • Can be used for welding of duplex to mild steel and duplex to stainless steel


  • Less possibility for joint failure during operation
  • Large application area



Directions for use

DC - polarity when welding. The label on each container fully identifies the contents, and also gives basic information on application areas. Complete information on each flux label, and instructions for use are given in the handbook for maritime welders.
