ASTM B564 Nickel 201 Flanges are high-purity, low-carbon nickel alloy flanges manufactured from UNS N02201 (Nickel Alloy 201). These flanges offer excellent corrosion resistance in caustic and reducing environments, and because of their low carbon content they resist graphitization at elevated temperatures above 315°C (600°F), unlike standard Nickel 200. Available in types such as Blind, Slip-On, Weld Neck, and Threaded, Nickel 201 flanges ensure durability, strength, and long service life in demanding chemical processing environments.
What are ASTM B564 Nickel 201 Flanges?
ASTM B564 Nickel 201 Flanges are forged flanges manufactured according to ASTM B564 specifications using commercially pure, low-carbon wrought nickel (UNS N02201). Nickel 201 is the low-carbon version of Nickel 200, developed specifically to retain ductility and avoid carbide precipitation (graphitization) when used above 315°C (600°F).
We supply a wide range of Nickel Flanges, including precision-engineered ASTM B564 UNS N02201 Flange products that meet international quality standards. Our experience in supplying flanges to caustic-handling and high-temperature chemical industries ensures consistent performance and reliability.
