Inconel 686 straight weld wires
Inconel 686 straight weld wires are a kind of nickel-based superalloy welding wires. They are designed for high corrosion and high-temperature environments. The chemical composition of Inconel 686 straight weld wires is based on nickel (Ni). Chromium (Cr), molybdenum (Mo) and tungsten (W) are added. They have excellent corrosion resistance and mechanical properties. Inconel 686 straight weld wires are easy for both automated welding and manual operation. They are suitable for TIG and MIG processes.
Inconel 686 straight weld wires are widely used in many fields. These fields include chemical industry (reactors, pipes), ocean engineering (seawater desalination equipment), energy (gas turbines, nuclear power) and environmental protection (flue gas desulfurization systems). The excellent corrosion resistance, high-temperature stability and welding performance of Inconel 686 straight weld wires make them the first choice for welding and repairing key equipment in extreme environments. They can ensure long-term reliable operation.
Features of Inconel 686 straight weld wires
Excellent corrosion resistance: Inconel 686 straight weld wires perform well in chloride, acidic media (like sulfuric acid and hydrochloric acid), and oxidizing-reducing mixed environments. They are much better than regular stainless steels.
High-temperature stability: Inconel 686 straight weld wires can work for a long time below 980°C. They have good oxidation resistance and thermal fatigue resistance.
Good weldability: Inconel 686 straight weld wires have low hot cracking sensitivity. The weld metal is compatible with base metals (such as Inconel 686, 625, or C-276). The weld bead is uniform.
High strength and toughness: The welded joint keeps high tensile strength and ductility. So Inconel 686 straight weld wires are suitable for dynamic load applications.
Applications of Inconel 686 straight weld wires
Chemical equipment: Inconel 686 straight weld wires are used in reactors, heat exchangers, and piping systems to resist strong acids and halide corrosion.
Marine engineering: Inconel 686 straight weld wires are used in seawater desalination devices and submarine parts to withstand salt spray and seawater erosion.
Energy sector: Inconel 686 straight weld wires are used in gas turbine components and nuclear power plant wastewater treatment systems to endure high-temperature and high-pressure corrosion.
Pollution control: Inconel 686 straight weld wires are used in flue gas desulfurization (FGD) systems and waste acid recovery equipment.
