Ni-Cr-Fe alloy is MIG welding wire and gives Ni-20Cr3Mn2,5Nb alloyed weld metal. It is especially used for welding Ni-Cr alloys such as Incoloy 800 with high creep strength, temperature and corrosion resistance, steels containing 5-9% Ni, cryogenic stainless steels used at temperatures as low as -196°C. It is used in the welding of different stainless steels, stainless steels and low alloyed steels and nickel alloys, buffer, plastering passes and coating welds on the surface of steels with low weldability. Welding metal has high crack resistance and corrosion resistance in acid, salt, liquid salt, oxidizing and carburizing atmospheres. In sulphurous atmospheres, weld metal should be used at temperatures lower than 500°C. It has a wide range of applications in chemical, petrochemical, glass, cement industries and repair and maintenance workshops and is generally used in LPG and LNG storage and processing plants, welding of furnace parts, burners, heat treatment equipment, cement kilns, molds, tanks, storage and transportation tanks of liquefied gases.
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
