Nickel 200 Pipe Fittings
Nickel 200 Pipe Fittings ( UNS N02200 )
Nickel 200 Pipe Fittings are manufactured from commercially pure wrought nickel (99.0% minimum) known for its exceptional corrosion resistance, high ductility, and superior thermal and electrical conductivity. These fittings are widely used in chemical processing, marine engineering, food processing, and high-temperature applications requiring excellent resistance to caustic alkalis and neutral salts.
Nickel 200 (UNS N02200) offers outstanding mechanical properties even at elevated temperatures and maintains structural stability across a wide temperature range. Its strong resistance to reducing chemicals and its ability to withstand severe corrosive environments make Nickel 200 Pipe Fittings a preferred choice across critical industrial sectors.
