1. What is Inconel 625 (N06625) used for?
Answer:
Inconel 625 is a nickel-chromium-molybdenum alloy with exceptional strength, corrosion resistance, and oxidation resistance at high temperatures. It is widely used in aerospace, chemical processing, marine engineering, and power generation, including turbine components, heat exchangers, pressure vessels, and marine hardware.
2. What are the key properties of Inconel 625 Plates?
Answer:
High corrosion resistance: Resists pitting, crevice corrosion, and stress corrosion cracking.
Excellent high-temperature strength: Maintains mechanical integrity in temperatures up to 1200°F (650°C).
Good weldability and fabricability: Can be welded, machined, and formed without losing strength.
Durability: Ideal for harsh environments, including saltwater and chemical exposure.
3. What is the chemical composition of N06625 Alloy?
Answer:
Nickel (Ni): 58% min
Chromium (Cr): 20–23%
Molybdenum (Mo): 8–10%
Iron (Fe): ≤5%
Niobium + Tantalum (Nb + Ta): 3.15–4.15%
Others (Mn, Si, C, Al, Ti): trace amounts
This composition gives superior corrosion resistance and high-temperature strength.
4. How is Inconel 625 Plate manufactured?
Answer:
Typically produced by hot rolling and annealing to achieve uniform mechanical properties.
Can be supplied in various thicknesses, widths, and lengths depending on application requirements.
Plates are often heat-treated to enhance strength and stress relief.
Surface finishes can vary: mill finish, polished, or shot-blasted depending on use.
5. How should Inconel 625 Plates be maintained?
Answer:
Keep plates clean and free of contaminants to prevent corrosion.
Avoid exposure to strong acids or harsh chemicals that may damage the surface.
Periodic inspection for oxidation or surface defects is recommended in high-temperature or marine environments.
Proper storage in dry, ventilated areas prevents discoloration or contamination.
