Known for its excellent resistance to caustic alkalis, organic chemicals, dry fluorine, and high-purity process environments, Nickel 200 is widely used in chemical processing, electronics, food processing, aerospace, and power generation industries.
Southerly Alloy supplies a complete range of Nickel 200 seamless pipe, Nickel 200 welded pipe, Nickel 200 seamless tube, and Nickel 200 welded tube manufactured in accordance with ASTM B161, ASTM B163, ASTM B725, and ASTM B730 standards. Available sizes include heat exchanger tubing, instrumentation tubing, process piping, and custom fabricated nickel alloy tubing solutions.
Compared with stainless steel materials, UNS N02200 nickel pipe provides superior resistance to caustic soda, chlorine-containing media, and alkaline environments while maintaining excellent thermal and electrical conductivity. Nickel 200 tubing is frequently specified for evaporators, heat exchangers, storage tanks, reactor vessels, and electronic component manufacturing systems where material purity and corrosion resistance are critical.

Frequently Asked Questions
Answers to common technical and purchasing questions about Nickel 200 pipe and tube products.
Both grades are commercially pure wrought nickel alloys. The primary difference is carbon content. Nickel 201 contains significantly lower carbon levels, reducing the risk of graphite precipitation at elevated temperatures. Nickel 200 is commonly used below 315°C (600°F), while Nickel 201 is generally preferred for higher-temperature service.
Nickel 200 is typically recommended for continuous service below approximately 315°C (600°F). At higher temperatures, prolonged exposure may lead to graphitization, which can affect material properties. For elevated-temperature applications, Nickel 201 is often the preferred alternative.
Yes. Nickel 200 provides excellent resistance to caustic alkalis and is widely used in chlor-alkali plants, sodium hydroxide production facilities, storage tanks, piping systems, and heat transfer equipment handling concentrated caustic solutions.
Nickel 200 offers good corrosion resistance in many marine environments and flowing seawater conditions. However, for long-term exposure to stagnant seawater or severe marine service, alloys such as Monel 400 are often considered due to their enhanced resistance to localized corrosion.
Standard supply typically includes EN 10204 3.1 Mill Test Certificates (MTC). Additional documentation such as PMI reports, dimensional inspection reports, hydrostatic test records, and third-party inspection certificates from SGS, BV, TUV, or other agencies can be provided upon request.
Yes. Custom outside diameters, wall thicknesses, cut lengths, coiled tubing, U-bent tubes, polished finishes, and project-specific requirements can be manufactured according to customer drawings, technical specifications, and international standards.
