1. What are Inconel 600, Inconel 625, and Incoloy 800, and what are their key properties?
Answer:
Inconel 600 (UNS N04400): Nickel-chromium alloy with excellent resistance to oxidation and corrosion in a wide range of environments, good mechanical properties at elevated temperatures.
Inconel 625 (UNS N06625): Nickel-chromium-molybdenum alloy with high strength, outstanding corrosion resistance, and excellent weldability, suitable for chemical, marine, and aerospace applications.
Incoloy 800 (UNS N08800 / N08820 / N08367): Nickel-iron-chromium alloy with good resistance to oxidation and carburization at high temperatures and excellent structural stability.
2. What forms and sizes are available?
Answer:
Forms: Sheets, plates, and nickel alloy sheets
Thickness: Typically 1–50 mm (customizable)
Dimensions: Standard plate sizes (e.g., 1000×2000 mm, 1500×3000 mm) or cut-to-size options
Available in hot-rolled, cold-rolled, and annealed conditions depending on customer requirements.
3. What industries use these nickel alloy sheets and plates?
Answer:
