Nickel Alloy 201 Flanges
AB Steel manufactures and exports Nickel Alloy 201 Flanges in India, supplying seamless flanges built for higher strength and better corrosion resistance than standard steel offers. These UNS N02201 Flanges are high-tensile-strength and sturdy in build. This is the reason plants specify these for machined components, pump shafts, fasteners, valves, and handles. Nickel Alloy 201 Flanges are manufactured in a regulated process with the best quality raw material, so each flange has uniform toughness and an extended service life.

Why Choose Nickel Alloy 201?
Low carbon content keeps the alloy stable during welding and high-temperature service, avoiding the carbide precipitation that weakens standard nickel 200. Corrosion resistance stays excellent across a wide range of chemical media, and the alloy handles caustic alkalis specifically well, a property that makes it a standard choice for caustic soda processing equipment. High thermal and electrical conductivity suit it for components where heat transfer or current flow matters. Better resistance to graphitization at elevated temperatures extends service life over standard nickel, and the alloy holds its mechanical properties reliably in high-temperature applications.
