Q: What are the main properties of Inconel 600 and Incoloy 825/718 plates?
A:
Inconel 600: Excellent oxidation and corrosion resistance, high-temperature strength up to ~700°C (1290°F), and resistance to stress-corrosion cracking.
Incoloy 825/718 (optional): Incoloy 825 has high resistance to acid corrosion and seawater, while Incoloy 718 offers exceptional creep and fatigue resistance at elevated temperatures.
Annealed condition: Improves ductility, reduces internal stresses, and prepares the plates for further fabrication.
Q: What industries commonly use these high-temperature nickel alloy plates?
A: They are widely used in:
Chemical and petrochemical processing
Power generation, including gas and steam turbines
Aerospace and high-temperature industrial applications
Marine and offshore environments
Q: Why is annealing important for these plates?
A: Annealing enhances ductility, relieves internal stresses from rolling or fabrication, improves corrosion resistance, and ensures the material is easier to cut, bend, or weld for industrial applications.
Q: What thicknesses and sizes are typically available?
A: Plates are available in various thicknesses and standard or custom sizes. Standard sizes can range from thin sheets (~1–5 mm) to thick plates (~50 mm or more), with optional cutting to customer specifications.
Q: How do I choose between Inconel 600, Incoloy 825, and Incoloy 718?
A: Selection depends on service environment:
Inconel 600: High-temperature oxidation and moderate corrosion resistance
Incoloy 825: Superior resistance to acids and seawater corrosion
Incoloy 718: High creep and fatigue strength at elevated temperatures
Consider annealing for easier fabrication and improved mechanical performance.
