ASTM B161 Nickel 200 UNS N02200 Seamless Pipes
ASTM B161 Nickel 200 (UNS N02200) seamless pipes are manufactured from commercially pure wrought nickel, offering excellent corrosion resistance, high thermal conductivity, and superior mechanical stability. With a minimum nickel content of 99.0%, Nickel 200 provides outstanding resistance to caustic alkalis, neutral salts, and reducing environments. These pipes are widely used in chemical processing, food handling, marine equipment, and high-temperature service due to their purity, toughness, and reliability.
