Ni-Cr-Fe alloyed GTA (TIG) welding rod, depositing Ni-20Cr3Mn2,5Nb weld metal. Especially used for welding of highly creep resistant, heat and corrosion resistant Ni-Cr alloys, like Incoloy 800, 5-9% Ni containing steels, cryogenic stainless steels down to -196°C. Also suitable for joining dissimilar materials as stainless steels to low alloyed steels, stainless steels to nickel alloys, buffering of difficult to weld steels cladding on steels and repair welds of them. Weld metal deposit is insensitive to cracks, has very good resistance to acids, salts and alkaline solutions, molten salt (e.g. cyanide) in oxidizing and carburization atmospheres. In sulphuroıus atmospheres the weld metal can be used up to 500°C. Generally used for welding on LPG and LNG processing and storing plants, oven parts, burners, heat treatment equipment, cement works, moulds, transport and storage tanks of liquid gases in chemical, petrochemical industries, glassworks, civil engineering, repairing and maintenance workshops.
