Nickel Fasteners

Nickel 200 is a commercially pure (99.6%) wrought nickel with resistance to a range of corrosive media and good mechanical properties. It possesses a good thermal, electrical and magneto strictive properties. Used for a variety of processing equipment, particularly to maintain product purity in handling foods, synthetic fibers and alkalis. Nickel 200 also has a low gas content and low vapor pressure.

NICKEL 200 (N02200) FINISHED HEX NUT 1/4-20

The fasteners made from this alloy are also known as Alloy 200 bolts and nuts as well as UNS N02200 fasteners. The characteristic of this alloy makes it popular in the food industry (handling) and petrochem (caustic) applications.

Nickel 200 is magnetic except at extremely elevated temperatures. It is resistant to most acids and used in the production of caustics.

From a mechanical performance perspective, Nickel 200 bolts have low hardness and good ductility, so they are tough, but not particularly strong (60-85 ksi UTS).

Common Applications for Nickel 200 Fasteners

  • Chemical Processing
  • Food Processing
  • Electrical and Sonic Devices (due to high electrical and thermal conductivity, as well as magnetostrictive properties)
  • Structural application that demands corrosion resistance
  • Salt Production (especially in applications that use sodium hydroxide and fluorine).

Corrosion Resistance:  Nickel 200 bolts, nuts and threaded rods provide a very good corrosion resistance to various corrosive environments. They provide an outstanding corrosion resistance to caustic alkaline solutions. Nevertheless, Nickel 200 fasteners cannot be successful when exposed to oxidizing salt solutions.
