Standard Welding Nickel Alloy Incoloy 925 926 825 800 Wire Per Kg Nickel Wire
Nickel-based alloy welding wires exhibit excellent resistance to reactive gases, harsh environments, and corrosive reducing acid media. They also possess high strength, good ductility, and the capability for cold and hot deformation, as well as weldability.
Consequently, they find extensive applications in industries such as petrochemicals, metallurgy, nuclear energy, marine development, aerospace, and aviation. These alloys are utilized to address engineering corrosion challenges that general stainless steel and other metals or non-metal materials cannot effectively tackle, making them crucial corrosion-resistant materials.
Nickel-based alloys are characterized by nickel serving as the base metal with the inclusion of alloying elements, offering corrosion resistance in specific environments. When classified based on their chemical composition, these alloys primarily include nickel, nickel-copper alloys, nickel-molybdenum (nickel-molybdenum-iron) alloys, nickel-chromium (nickel-chromium-iron) alloys, nickel-chromium-molybdenum alloys (comprising nickel-chromium-molybdenum and nickel-chromium-molybdenum-copper alloys), and nickel-iron-chromium (iron-nickel-based) alloys.
Pure nickel welding wire ERNi-1 is employed for welding nickel alloys 200 and 201, as well as nickel-plated steel sheets; welding dissimilar materials such as steel and nickel; and surface cladding of steel. Nickel-copper welding wire ERNiCu-7 is utilized for welding Monel 400 alloy itself; welding Monel 400 alloy with steel; and surface cladding of steel.
