Nickel 201 flanges are low-carbon nickel alloy connectors built for applications where standard nickel or stainless flanges can't handle the combination of caustic exposure and elevated temperature. Amco Metals manufactures and exports these flanges for chemical processing, caustic soda production, and food processing equipment, where corrosion resistance and stable mechanical performance at temperature both matter. The low-carbon composition is what sets this grade apart it prevents the carbide precipitation that limits standard Nickel 200 in high-temperature service.


What are Nickel 201 Flanges?

Nickel 201 flanges are machined or forged from commercially pure nickel with a reduced carbon content, typically below 0.02%. That low-carbon specification prevents graphitization at temperatures above 315°C (600°F), which is exactly where standard Nickel 200 starts to lose reliability. The result is a flange that holds up in sustained high-temperature service without the embrittlement that would otherwise limit its use.

Features & Benefits

  • Excellent resistance to caustic alkalis, particularly sodium and potassium hydroxide at high concentrations
  • Stable mechanical properties across a wide temperature range, including cryogenic service
  • Low carbon content prevents graphitization above 600°F
  • Good weldability and ease of fabrication
  • High thermal and electrical conductivity compared to other nickel alloys

Standards

Nickel 201 flanges are in accordance with ASTM B160, ASTM B564 and ASME SB564 material specifications. They conform to ASME B16.5 dimensions for standard configurations and pressure classes for reliable performance, precise industrial interchangeability and safe operating conformity for demanding, high temperature, and corrosive service applications.

Testing & Certification

Each batch is tested for chemical composition, mechanically tested for properties and dimensionally inspected before it is shipped from our factory. We also supply Mill Test Certificates (MTC) in accordance with EN 10204/3.1 on request and third party inspection reports as required by the customer project specifications.

Manufacturing Process

The commercially pure nickel bar stock is forged into rough flange forms under controlled temperature to preserve the alloy’s low-carbon integrity. Each flange is machined to exact ASME B16.5 dimensions, including bolt hole patterns and face finish. Then the flanges are heat-treated wherever required. After that, the final inspection is carried out on the surface finish, dimensional accuracy, and material certification before packing.

Why Choose Nickel 201 Flanges?

Nickel 201 remains the preferred choice wherever caustic exposure meets elevated temperature a combination that degrades standard nickel and many stainless grades faster than expected. Its low-carbon composition, reliable weldability, and consistent mechanical performance make it a dependable specification for engineers designing caustic soda plants, chemical reactors, and food-grade processing lines that need to run for years without unplanned flange replacement.
