Corrosion Resistance

• Resistance to Oxidizing Media: Effective against acids (e.g., nitric acid) and chloride solutions.
• Resistance to Reducing Media: Performs well in environments containing sulfur compounds.
• Creep and Fatigue Resistance: Maintains structural integrity under long-term high-temperature and stress loads.

High-Temperature Performance

• It can withstand continuous service temperatures up to 1093°C, with minimal loss of strength.
• Suitable for applications such as furnace components, gas turbine parts, and chemical processing equipment.

Fabrication and Processing

• Welding: Can be welded by various methods (e.g., TIG, MIG, and resistance welding) without significant loss of corrosion resistance.
• Machining: Requires proper tooling and cooling due to its high work-hardening rate.
• Forming: Can be cold-formed in annealed condition, though heavy forming may require intermediate annealing.

Standards and Equivalents

• DIN Standard: DIN 2.4819
• Equivalent Standards:
  • ASTM: N06625
  • ISO: W.Nr. 2.4856
  • UNS: N06625

Typical Applications

• Aerospace: Engine components and exhaust systems.
• Marine Engineering: Corrosion-resistant parts in seawater environments.
• Chemical Industry: Reactors, heat exchangers, and pipes for handling corrosive media.
• Oil and Gas: Offshore platforms and high-pressure pipelines.

Surface and Heat Treatment

• Usually supplied in annealed condition with a mill-finished surface.
• Solution annealing (at 1093–1204°C followed by rapid cooling) can optimize its ductility and corrosion resistance.
