Product Overview
Introduction To Nickel 201 / Alloy 201 / UNS N02201
MOKSH TUBES & FITTINGS LLP is a leading manufacturer, supplier, exporter, importer, and stockist of NICKEL 201 products, offering Pipes & Tubes, Pipe Fittings, Flanges, Fasteners, Sheets, Plates, Coils, Wires, Round Bars, Flat Bars, Angles, Channels, Welding Rods, Wire Mesh, and other customized and specialty Nickel 201 components.
Nickel 201, is a low-carbon version of commercially pure wrought nickel (99.6% Ni), designed to provide enhanced resistance to graphitization in high-temperature environments. It retains the excellent corrosion resistance, thermal and electrical conductivity, and workability of Nickel 200 while offering superior performance in applications above 600 °F (315 °C). The reduced carbon content (0.02% max) minimizes carbide precipitation and ensures resistance to intergranular attack—making Nickel 201 ideal for caustic, food-grade, and high-temperature service environments.
