Nickel 200 doesn't rely on a complicated alloy recipe to do its job. At 99.0% nickel minimum, it's about as close to pure metal as a piping specification gets, and that simplicity is exactly what makes it valuable: no chromium, no molybdenum, nothing for caustic soda or food product to react with. USA Piping Solution supplies it as seamless pipe and tube to ASTM B161, welded pipe to ASTM B725, and condenser tube to ASTM B163, all in UNS N02200. For the low-carbon version built for high-temperature service, see our Nickel 201 Pipes & Tubes page.

Applications
Nickel 200's value is versatility: it shows up wherever a process can't tolerate the alloying elements in stainless or nickel-chromium grades reacting with the product or the environment.
- Caustic Soda (NaOH) Handling: piping and equipment in chlor-alkali and caustic processing, where nickel's resistance to caustic corrosion is close to unmatched.
- Food Processing Equipment: piping and vessels where the material must not affect taste, color, or purity of the product.
- Chemical Processing: general corrosive service outside strong oxidizing acids.
- Electrical & Electronic Components: parts relying on nickel's low electrical resistivity.
- Marine Hardware: fittings and components in seawater-adjacent service.
When to Step Up to Nickel 201
Nickel 200 covers the large majority of commercially pure nickel piping needs. Step up to Nickel 201 specifically when service runs hot: above roughly 600°F (315°C), Nickel 200's carbon content can form graphite at grain boundaries and embrittle the material over time. Below that temperature, Nickel 200 is the more common and more economical choice.

Frequently Asked Questions
What's the difference between Nickel 200 and Nickel 201?
Carbon content. Nickel 200 allows up to 0.15% carbon; Nickel 201 caps it at 0.02%. The lower carbon in 201 prevents graphite forming at grain boundaries above roughly 600°F, which is why it's the elevated-temperature choice.
Is Nickel 200 suitable for caustic soda service?
Yes, it's one of the standard materials for caustic soda handling below roughly 600°F, where it resists caustic corrosion better than most stainless or nickel-chromium alloys.
Is Nickel 200 food-safe?
Yes, it's commonly used in food processing equipment because it doesn't affect the taste, color, or purity of the product it contacts.
What sizes are available in Nickel 200 pipe and tube?
We supply from 1/8" NB to 48" NB across Schedule 5 to Schedule XXS. Send us your requirement and we'll confirm current availability.
