Nickel-based alloy welding wire has good properties of resisting active gas, caustic medium, reducing acid medium corrosion, high strength, good plasticity, cold and hot deformation, processing and welding. Therefore, it is widely used in petrochemical industry, metallurgy, atomic energy, ocean development, aviation, aerospace and other industries.
Also it is a very important corrosion-resistant metal material to solve the engineering corrosion problem which can not be solved by ordinary stainless steel and other metals and non-metallic materials. Nickel-based alloys are alloys based on nickel and containing alloying elements, which can resist corrosion in some media.
According to its chemical composition, there are mainly pure nickel, nickel-copper alloy, nickel-molybdenum (nickel-molybdenum-iron) alloy, nickel-chromium (nickel-chromium-iron) alloy, nickel-chromium-molybdenum (including nickel-chromium-molybdenum alloy and nickel-chromium-molybdenum-copper alloy) and Nickel-Iron-Chromium (both ferronickel-based).
