Nickel 201 is a commercially pure wrought nickel with controlled low carbon content (0.02% maximum), specifically formulated to prevent graphitization and embrittlement at temperatures above 315°C (600°F). It offers excellent resistance to caustic alkalis, dry gases, and many corrosive environments while maintaining good thermal and electrical conductivity. For service below 315°C, Nickel 200 provides similar properties at lower cost . 1.

2.Fabrication & Material ComparisonNickel 201 offers excellent fabricability, similar to austenitic stainless steels, but requires more powerful equipment for forming operations due to its higher strength. Hot Working Range: 649-1232°C (1200-2250°F); heavy forming operations recommended above 871°C (1600°F) . Avoid working in the 538-760°C range (embrittlement risk). Cold Working: Excellent response to bending, stamping, drawing, and forming; work-hardening rate higher than carbon steel, requiring intermediate anneals for severe deformation . Annealing: 704-871°C (1300-1600°F), time at temperature depends on section size; rapid cooling not required . Machining: Similar to soft steel but with higher work-hardening rate; requires sharp tools, positive feeds, and heavy-duty lubricants . Welding: Excellent weldability using GTAW, GMAW, SMAW, and resistance welding; matching filler metal (ERNi-1) recommended. Surface must be clean and free of sulfur, lead, and other contaminants .
Applications Chemical Processing: Caustic evaporators, storage tanks, piping systems for sodium hydroxide and potassium hydroxide at elevated temperatures; reactor vessels for organic processes; handling equipment for fatty acids and phenols Aerospace & Defense: Rocket motor cases, missile components, thrust chambers, high-temperature structural parts Food & Pharmaceutical: Equipment requiring product purity at elevated temperatures; processing vessels; cleaning system components Electronics: Electronic tube parts, transducer components, specialized electrical applications Industrial Manufacturing: Combustion boats, plater bars, thermocouple sheaths, high-temperature fixtures
