Critical Applications of Nickel 200 Fasteners
Chemical Processing
Nickel 200 fasteners are extensively used in chemical processing plants due to their outstanding resistance to caustic alkalis (sodium hydroxide, potassium hydroxide) up to and including molten state. They resist corrosion in de-aerated acid environments and maintain product purity in handling foods, synthetic fibers, and alkalies. Applications include reactors, tanks, piping systems, heat exchangers, and evaporators handling caustic soda and hydrofluoric acid.
Marine & Offshore
Nickel 200 fasteners resist ordinary seawater corrosion, making them ideal for onshore and offshore marine applications. Used in seawater desalination systems, marine fittings, and corrosion-resistant fasteners for vessels and offshore platforms. Excellent resistance to neutral and alkaline salt solutions ensures long-term reliability in marine environments.
Aerospace & Defense
Nickel 200 fasteners are used in aircraft components, rocket motor cases, and missile systems where high purity and corrosion resistance are essential. Non-magnetic properties and low outgassing make them suitable for sensitive instrumentation and vacuum tubes. Maintains ductility from cryogenic temperatures to 600°F, ensuring reliable performance across extreme thermal environments.
Power Generation
Nickel 200 fasteners in nuclear reactors, steam turbine controls, and power plant cooling systems provide reliable fastening in corrosive and high-temperature environments. Resists corrosion by liquid metal coolants and maintains mechanical properties up to 315°C (600°F). Used for turbine control linkages, sensor mounts, and heat exchanger bolting where corrosion resistance and product purity are critical.
Food & Pharmaceutical
Nickel 200 fasteners are used in food processing equipment and pharmaceutical machinery due to non-reactivity with organic materials and ability to maintain product purity. Excellent resistance to organic compounds and caustic cleaning solutions ensures long service life in hygienic applications. Used in equipment for food handling, dairy processing, and pharmaceutical manufacturing where contamination must be avoided.
Electronics & Battery Manufacturing
Nickel 200 fasteners are used in electronic components, battery manufacturing equipment, and magnetostrictive devices. High electrical conductivity (0.096 μΩ·m) and excellent fabricating characteristics make them ideal for sonar devices, ultrasonic welding controls, and rechargeable battery production. Used in computers, mobile phones, electric tools, and camcorders.

Nickel 200 (UNS N02200) – Minimum 99.2% Nickel
Metallurgical note: Nickel 200 is a commercially pure, solid-solution wrought nickel alloy. It has a face-centered cubic (FCC) crystal structure that remains stable from cryogenic temperatures up to its melting point, providing excellent ductility and fabricability. The alloy exhibits ferromagnetic properties with a Curie temperature of approximately 360°C (680°F). Nickel 200 is suitable for applications up to 315°C (600°F); for higher temperatures, Nickel 201 (low carbon version) is recommended to avoid graphitization.

Physical Properties – Nickel 200
High‑Temperature Performance of Nickel 200 Fasteners
Nickel 200 retains useful mechanical properties at elevated temperatures up to 315°C (600°F) and is suitable for continuous service in this range. The alloy maintains excellent ductility from cryogenic temperatures (-269°C) up to its maximum service temperature, with no ductile-to-brittle transition. At elevated temperatures, Nickel 200 exhibits good oxidation resistance and retains approximately 50% of its room temperature strength at 315°C. For applications above 315°C, Nickel 201 (low carbon version) is recommended to prevent graphitization and embrittlement.
