Nickel 201 (UNS N02201) Plates are the low-carbon modification of Nickel 200, specifically engineered for applications where exposure to temperatures exceeding 315°C (600°F) is required. Produced under the ASTM B162 specification, Nickel 201 limits carbon content to a maximum of 0.02%. This critical adjustment prevents the formation of intergranular graphite (graphitization) at elevated temperatures, which would otherwise lead to severe embrittlement and material failure in standard nickel grades. As a commercially pure wrought alloy, it retains the exceptional corrosion resistance of its counterpart while providing enhanced thermal stability up to 600°C (1100°F).

The primary industrial advantage of ASTM B162 Nickel 201 is its unmatched performance in high-temperature caustic environments. It is the definitive material of choice for caustic soda evaporators and chemical reactors where purity and structural integrity are paramount. Beyond its chemical resistance, Nickel 201 is slightly softer than Nickel 200, offering superior ductility that facilitates complex cold-forming and deep-drawing operations. Its high thermal and electrical conductivity, combined with low magnetostriction, makes it highly effective for electronic components, aerospace heat shields, laboratory equipment, and synthetic fiber production. By utilizing Nickel 201, engineers can ensure long-term reliability in thermal processing environments that would compromise other metallic materials.

Nickel 201 B162 Plate Features

» Low-Carbon Stability: With a carbon content limited to 0.02% max, it eliminates the risk of intergranular embrittlement caused by graphitization at high temperatures.
» High-Temperature Reliability: Ideally suited for continuous service in environments exceeding 315°C (600°F), maintaining structural integrity up to 600°C (1100°F).
» Exceptional Caustic Resistance: Offers the highest degree of resistance to caustic alkalis, particularly sodium hydroxide and potassium hydroxide, across all concentrations.
» Enhanced Ductility: Being slightly softer than Nickel 200, it provides superior workability for complex fabrication, deep drawing, and spinning processes.
» Superior Thermal Conductivity: High heat transfer efficiency makes it an excellent choice for heat exchangers and high-temperature processing vessels.
» Resistance to Halogens: Demonstrates outstanding resistance to dry fluorine and is widely used in the handling of chlorine and hydrogen chloride at elevated temperatures.
» Vacuum Compatibility: Maintains low vapor pressure and low gas content, ensuring clean performance in high-vacuum and electronic applications.
» Ease of Welding: Can be readily welded using standard methods like GTAW and GMAW, provided the appropriate low-carbon filler metals are utilized.
