DIN M. No.


Ni-Cr-Mo alloyed GMA (MIG) welding wire, depositing Ni-22Cr9Mo3,5Nb weld metal. Used for welding of highly corrosion resistant Ni-Cr-Mo alloys, like Alloy 625, 825 and similar alloys. Due to it's good cryogenic toughness down to -196°C, preferred for welding of cyrogenic nickel alloys, e.g. X1NiCrMoCuN25-20-7. In sulphur free atmospheres the weld metal is non-scaling up to 1200°C, in sulphurous atmospheres the weld metal can be used in service temperatures up to 500°C. It is also highly resistant stress corrosion cracking and pitting corrosion in phosphoric acid, organic acids, sea water and polluting environments. Weld metal is insensitive to cracking and very resistant to thermal shocks. Used for joining of dissimilar nickel alloys, joining dissimilar stainless steels, low alloyed steels to stainless steels or to nickel alloys, buffering of difficult to weld steels and repair welding of them.Stick Electrode : ENI 425TIG Welding Rod: TNI 425
