When selecting nickel-based alloy products, several key factors need to be considered, incorporating relevant nickel-based alloy products into each factor:

  1. Corrosion Resistance: For corrosion resistance, some exemplary nickel-based alloy products include:

    • Nickel-based corrosion-resistant alloys such as Inconel 625, Hastelloy C276, which exhibit excellent resistance to acids, alkalis, and salt corrosion, widely used in the chemical industry.
    • Incoloy 800 series products like Incoloy 800H, which possess good oxidation and sulfidation resistance, suitable for sulfurous acidic environments under high temperature and pressure.
    • Monel alloys such as Monel 400, known for their excellent resistance to corrosion in seawater, brine, and other corrosive media, commonly used in marine engineering and chemical industries.
  2. High-Temperature Performance: For high-temperature performance, typical nickel-based alloy products include:

    • Inconel 718, known for its excellent high-temperature strength and heat resistance, frequently used in high-temperature components in the aerospace industry.
    • Nimonic series alloys like Nimonic 80A, offering outstanding high-temperature strength and oxidation resistance, suitable for manufacturing critical engine components operating at high temperatures.
    • Rene series alloys such as Rene 41, known for their extremely high high-temperature strength and oxidation resistance, commonly used in key components of aerospace engines.
  3. Mechanical Properties: For mechanical properties, typical nickel-based alloy products include:

    • Waspaloy alloy, renowned for its excellent high-temperature strength and fatigue resistance, commonly used in high-temperature blades and impellers in the aerospace industry.
    • Inconel 625, besides its excellent corrosion resistance, also exhibits good mechanical properties, suitable for environments with high temperature and corrosion.
    • Haynes series alloys like Haynes 230, offering high-temperature strength and oxidation resistance, suitable for engineering components operating at high temperatures.
  4. Machinability: For machinability, most nickel-based alloy products demonstrate good machinability and can undergo processes such as welding, forging, and machining.

  5. Cost-effectiveness: In terms of cost-effectiveness, it's essential to balance the performance and price of nickel-based alloy products to choose products that fit the budget and meet requirements.

  6. Supply Stability: Select nickel-based alloy product suppliers with stable supply channels and reliable brands to ensure continuous product availability.

  7. Application Environment Requirements: According to specific application scenarios and environmental requirements, choose suitable nickel-based alloy products, such as those with requirements for corrosion resistance, high temperature resistance, wear resistance, etc.

In summary, the above key factors are all crucial when selecting nickel-based alloy products, and they need to be considered comprehensively to meet procurement needs.
