Nickel 200 / 201 Pipe Fittings – Manufacturer, Supplier & Exporter in Mumbai, India

What are Nickel 200 / 201 Pipe Fittings?

Nickel 200 (UNS N02200) and Nickel 201 (UNS N02201) are commercially pure wrought nickel alloys known for their excellent corrosion resistance and high thermal and electrical conductivity.

• Nickel 200 contains higher carbon content and is suitable for moderate temperatures
• Nickel 201 has lower carbon content, making it ideal for high-temperature applications where embrittlement must be avoided

These alloys provide:

• Excellent resistance to alkalis and neutral salts
• Good resistance to organic acids
• Outstanding performance in reducing environments

Nickel 200/201 pipe fittings are widely used in applications requiring purity, corrosion resistance, and reliability.
