Nickel 200 (UNS N02200) is a commercially pure nickel. It provides a reliable solution for specific needs. It’s especially useful in caustic soda and alkaline solutions. Standard stainless steel often lacks the needed endurance. It can also struggle with corrosion. It ensures your stainless steel pipes and stainless steel pipe fittings last.
What is Nickel 200 | UNS N02200 : A Pure Material!
Nickel 200 contains a minimum of 99.6% nickel. This high purity gives it excellent resistance.It has corrosion resistance in a variety of environments, is non-magnetic, has good mechanical properties, and is resistant to oxidation and carburization. This makes Nickel 200 a top choice.
Key Advantages of Nickel 200
Nickel 200 has high corrosion resistance and can withstand strong alkaline substances,as well as resisting a variety of organic and inorganic compounds.
It retains its strengh at all temperatures and does not soften.
It is an excellent heat conduction material and also has good electrical conductivity.This makes it widely applicable in electronic components.
This pure nickel is easy to form and can be welded easily. It simplifies complex manufacturing processes and ensures strong and reliable connections in piping systems.

Nickel 200 in Piping Systems
- Alkaline Systems: Used for processing caustic soda because it can withstand high-temperature alkaline substances.
- Food Processing: Food processing equipment.Its high purity prevents contamination and is safe for human consumption.
- Chemical Processing: It can handle strong acids and certain organic acids since it resists stress corrosion cracking.
- Electrical Components: Its excellent electrical properties make it suitable for use in electronic components.
- Piping Systems: Essential stainless steel pipe fittings require extremely strong corrosion resistance.
Sourcing and Fabricating Inconel 600
A complete Material Test Report (MTR) is required. It verifies the precise composition of the alloy and ensures its performance.
Work with specialized suppliers of stainless steel pipe and fittings. They understand these alloy steels and can ensure proper fabrication and quality control,and are ISO 9001 and CE-PED certified.
This alloy requires specific procedures. Proper welding technique ensures the integrity of the weld.
It is expensive, so it is important to assess whether the product has a longer service life. This can justify its higher initial cost.
