Properties And Applications
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.
