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.
