1. Nickel Alloy 201 Chemical Composition/wt%:
Ni≥99, C≤0.02, Cu≤0.25, Si≤0.3, Mn≤0.35, S≤0.01, Fe≤0.4, Cr≤0.2
2. Nickel Alloy 201 Processing Performance:
Cold working: The work hardening rate is relatively low, and it is easy to process using standard tools. However, for large deformation processing, intermediate annealing is required to restore plasticity.
Hot working: The recommended hot forging temperature range is 870-1230°C, and conventional methods such as TIG and MIG can be used.
Machining: The material is relatively soft and sticky, so high-speed steel tools are recommended.
3. Nickel Alloy 201 Heat Treatment Process
Heat treatment process for plates, strips, and foils:
(1) Annealing (intermediate/finished product); Typical temperature process parameters: 700-900°C, Purpose: To eliminate work hardening and restore plasticity.
(2) Solution treatment: Typical temperature parameters: 950-1205°C. Purpose: To optimize the structure and improve corrosion resistance.
Heat treatment process for rods, wires, and filaments:
(1) Annealing; Typical temperature process parameters: 700-900°C, Purpose: To eliminate stress and adjust performance.
(2) Solution treatment: Typical temperature parameters: 600-750°C. Purpose: To reduce residual stress and prevent deformation and cracking.
Note: Due to the extremely low carbon content of Ni201, its annealing temperature should be about 30-55°C lower than that of Ni200, or the holding time should be appropriately shortened to prevent excessive grain growth.
4. Nickel Alloy 201 Application Fields:
Chemical and alkali industry: Chemical reactors and heat exchangers, caustic soda processing equipment, organic/inorganic chloride and fluoride production equipment, catalytic regenerators.
Food processing and pharmaceuticals: Food processing equipment, salt refining equipment, reactors and dryers in the pharmaceutical industry.
