ASTM B163 Alloy 201 / UNS N02201 Seamless Nickel Tube Heat Exchanger Tube

ASTM B163 / ASME SB163 UNS N02201 / Alloy 201 Seamless Nickel Tube

ASME SB163 UNS N02201 (Nickel 201) tubes are the engineered solution for the most challenging environments. With a minimum 99.0% nickel content, this low-carbon grade is the go-to material for resisting corrosion from caustics and high-purity water. This commercially pure nickel excels in caustic environments, high-purity water, and organic acids, outperforming stainless steels. It's essential for chemical processing, heat exchangers, and semiconductor manufacturing.

Key Advantages of ASTM B163 UNS N02201 / Nickel 201 Seamless Tube

•  Excellent Corrosion Resistance: Perfect for handling caustic alkalies, high-purity water, and various organic acids.
•  Superior Thermal Stability: Maintains integrity in continuous service up to 600°F (315°C).
•  Low Carbon Content (<0.02%): Prevents "graphitization" and embrittlement in high-temperature applications.
•  ASME SB163 Certified: Guaranteed quality, dimensional accuracy, and material traceability.
