Incoloy 20 Polished Bar

Incoloy 20 polished bar

Incoloy 20 polished bar is a nickel-iron-chromium-based high-grade alloy. It is made more corrosion-resistant by adding copper and molybdenum. Niobium is used to stabilize it and reduce carbide precipitation. The bar is shaped by precision cold drawing or hot rolling. Its surface is mechanically polished to a mirror or matte finish. It has high-precision dimensions with tolerances controlled within ±0.05 mm and excellent surface finish (Ra≤0.8μm). Incoloy 20 polished bar is used to make key parts in harsh corrosive environments.

Incoloy 20 polished bar is widely used in many fields. In the chemical industry, it is used for sulfuric acid evaporators and reactors. In marine engineering, it is used for seawater desalination pumps and valves. In food processing, it is used for acid-resistant pipes. In nuclear waste treatment, it is used for radiation-resistant structural parts. It has excellent corrosion resistance (especially in mixed acid environments), high-temperature stability (can be used for a long time at 500℃), and it is FDA compliant. These features make Incoloy 20 polished bar a key material in tough working conditions. It can greatly extend the life of equipment and reduce maintenance costs.

Features of Incoloy 20 polished bar

Superior Corrosion Resistance:

Incoloy 20 polished bar is much more corrosion-resistant than 316L in sulfuric acid, phosphoric acid and mixed acid environments (like 70% sulfuric acid at 50℃). Its threshold for chloride stress corrosion cracking is over three times that of 304 alloy.

The addition of copper (3-4%) helps Incoloy 20 polished bar form a passive film in reducing acids (such as dilute sulfuric acid). The annual corrosion rate is less than 0.1 mm.

High-Temperature Stability:

Incoloy 20 polished bar can work continuously at 500℃ (up to 600℃ in the short term). It remains phase-stable in thermal cycling conditions and shows no tendency to σ-phase embrittlement.

Process Compatibility:

The polished surface of Incoloy 20 polished bar can reduce fluid resistance by 40%. It is especially suitable for transporting high-purity media.

Incoloy 20 polished bar has a moderate cold working hardening rate (with a work hardening index n=0.25). It can be deep-drawn into shape.

Applications of Incoloy 20 polished bar

Chemical Equipment: Incoloy 20 polished bar is used to make heating tubes for concentrated sulfuric acid evaporators (with a 20% longer service life than Hastelloy C276) and agitator shafts for reactors in the pharmaceutical industry.

Marine Engineering: Incoloy 20 polished bar is used for high-pressure pump valve stems in seawater desalination plants. The annual pitting depth in a 6% NaCl solution is less than 0.02 mm.

Food Processing: Incoloy 20 polished bar meets FDA standards and is used as a support for high-temperature acidification pipes in tomato sauce production lines.

Nuclear Waste Treatment: The niobium-stabilized feature of Incoloy 20 polished bar makes it an ideal structural material for nuclear waste liquid concentration equipment. It has excellent resistance to irradiation swelling.
