Incoloy 20 straight weld wires
Incoloy 20 straight weld wires are nickel-iron-chromium austenitic alloy welding wires. They are designed for welding the same kind of metal or different metals. The wires have copper and molybdenum (Nb) added to them. This makes them have great corrosion resistance and high-temperature stability. The straight shape of the wires makes them easy to use in automatic or semi-automatic welding processes like TIG and MIG. They make sure the weld metal matches the base metal in performance. They are good for high-precision welding in tough environments.
Incoloy 20 straight weld wires are used in many areas. These include chemical industry (sulfuric acid reactors, acid pickling equipment), marine engineering (seawater treatment systems, subsea pipelines), energy (flue gas desulfurization devices, nuclear fuel processing), and food and pharmaceutical (high-purity piping). Their excellent corrosion resistance, high-temperature stability, and welding compatibility make equipment last longer and safer in harsh conditions.
Features of Incoloy 20 straight weld wires
Excellent corrosion resistance: Incoloy 20 straight weld wires are very resistant to sulfuric acid, phosphoric acid and chloride stress corrosion cracking (SCC). They perform well in chemical and marine environments.
High-temperature stability: Incoloy 20 straight weld wires keep their strength below 600°C. They are more oxidation-resistant than 304/316 stainless steel.
Process adaptability: Incoloy 20 straight weld wires have low hot cracking sensitivity and good weld fluidity. They are suitable for multi-layer welding of thin and thick plates.
Compatibility with dissimilar metals: Incoloy 20 straight weld wires can be used to weld nickel-based alloys and stainless steel. They reduce the risk of weld embrittlement.
Applications of Incoloy 20 straight weld wires
Chemical equipment: Incoloy 20 straight weld wires are used for key welds in sulfuric acid reactors, phosphoric acid production pipes and acid pickling equipment.
Marine engineering: Incoloy 20 straight weld wires are used for anti-corrosion welding in seawater treatment systems and subsea pipelines.
Energy sector: Incoloy 20 straight weld wires are used for acid-resistant parts in flue gas desulfurization (FGD) systems and nuclear fuel processing equipment.
Food and pharmaceutical: Incoloy 20 straight weld wires are used for high-purity medium transport pipes. They meet both hygiene and chemical resistance standards.
