Incoloy 28 straight weld wires
Incoloy 28 straight weld wires are nickel-based alloy weld wires. They are designed for highly corrosive environments. The main components are nickel (Ni), chromium (Cr), molybdenum (Mo), and copper (Cu). Iron (Fe) is added as a balancing element. The straight weld wires are made by cold drawing. They have precise diameter tolerances and excellent surface finish. They are suitable for both automated and manual welding processes, like TIG, MIG, and plasma arc welding (PAW).
Incoloy 28 straight weld wires are widely used in oil and gas (acidic environment pipelines), chemical (sulfuric/phosphoric acid equipment), environmental protection (flue gas desulfurization systems), and marine engineering (salt spray-resistant parts). Their excellent corrosion resistance, high-temperature stability, and welding performance can effectively enhance the durability of equipment in harsh conditions and reduce maintenance costs.
Features of Incoloy 28 straight weld wires
Excellent Corrosion Resistance:
Incoloy 28 straight weld wires perform well in strong corrosive media like sulfuric acid, phosphoric acid and chlorides. They are especially suitable for acidic oil and gas fields and chemical environments.
They have outstanding resistance to pitting, crevice corrosion and stress corrosion cracking (SCC).
High-Temperature Stability:
Incoloy 28 straight weld wires can keep mechanical properties and oxidation resistance at high temperatures (up to 600°C). They are suitable for welding heat exchangers and high-temperature pipes.
Good Welding Processability:
Incoloy 28 straight weld wires have low sensitivity to hot cracking. The welding pool has good fluidity and the weld bead is uniform. This reduces the risk of porosity and slag inclusion.
Wide Compatibility:
Incoloy 28 straight weld wires can be used to weld many kinds of nickel-based alloys, such as Incoloy 825 and 904L. They can also be used for welding dissimilar metals.
Applications of Incoloy 28 straight weld wires
Oil and Gas: Incoloy 28 straight weld wires are used to weld subsea pipelines and sour gas treatment equipment. They can resist corrosion from hydrogen sulfide (H₂S) and carbon dioxide (CO₂).
Chemical Industry: Incoloy 28 straight weld wires are used to make sulfuric acid reactors, phosphoric acid evaporators and containers with chloride media.
Environmental and Energy: Incoloy 28 straight weld wires are used to weld corrosion-resistant parts in flue gas desulfurization (FGD) systems and nuclear waste treatment equipment.
Marine Engineering: Incoloy 28 straight weld wires are used to repair seawater cooling systems or marine pumps and valves. They can resist salt spray erosion.
