Nickel alloy 625 welded coiled tube is a welded coiled tube made of nickel alloy 625, a nickel-chromium-molybdenum alloy containing elements such as Niobium, Titanium, and Aluminum, which provides a good combination of properties. nickel alloy 625 welded coiled tube It is a continuous small diameter pipe made by cutting nickel alloy 625 material into strips and then welding, cold drawing and coiling.
Material Advantage Characteristics:
High nickel content: the Nickel content is up to about 58%, it is a high nickel alloy with good corrosion resistance and high temperature resistance.
Moderate chromium content: Chromium content of 20% to 23%, with good oxidizing and reducing properties, can form a stable passivation film to prevent further corrosion.
High molybdenum content: Molybdenum content of 8% ~ 10%, with good resistance to pitting corrosion and stress corrosion cracking, able to resist chloride and other media erosion.
High niobium content: Niobium content of 3% ~ 4%, with good creep resistance and fatigue resistance, able to maintain high strength and toughness at high temperatures.
Low titanium and aluminum content: Titanium and Aluminum content of 0.4% and 0.4% or less respectively, is a low titanium aluminum alloy, has good weldability, will not produce cracks and embrittlement.
