Frequently Asked Questions
What is the price of Incoloy 825 Plate per kg?
Incoloy 825 plate price ranges from Rs. 1,400 to Rs. 3,000 per kg in India and approximately $30 to $50 per kg internationally. The final price depends on thickness, quantity, mill origin, and current nickel market rates.
Is Incoloy 825 Plate NACE MR0175 compliant?
Yes. UNS N08825 is listed in NACE MR0175 / ISO 15156 for use in H2S-containing oil and gas environments. This makes the 825 Plate a qualified choice for sour service where bid compliance requires NACE certification.
What is the maximum service temperature for Incoloy 825 plate?
The recommended maximum continuous service temperature is 540°C (1,000°F). Exposure above this range changes the metal’s internal structure, making it less flexible and more likely to break on impact.
What is the unit weight of Incoloy 825 plate?
Density of Incoloy 825 is 8.14 g/cm³ (0.294 lb/in³). Weight (kg) = Thickness (mm) × Width (m) × Length (m) × 8.14. Example: A 10 mm × 1,200 mm × 3,000 mm plate = 10 × 1.2 × 3.0 × 8.14 = 293 kg.
