Nickel Alloy 625 (UNS N06625) is a corrosion- and high-temperature-resistant superalloy composed primarily of nickel, chromium, molybdenum, and niobium. Renowned for its exceptional fatigue strength, resistance to seawater corrosion, and thermal stability, Inconel 625 plate is widely used in sectors such as aerospace, chemical processing, marine engineering, the nuclear industry, and offshore oil and gas. As of 2026, the price of Nickel Alloy 625 plate varies based on thickness, surface finish, certification standards, and the supplier's location. This guide outlines current pricing for Alloy 625 plate, classifications by specification, and the various factors influencing costs.

Nickel Alloy 625 Plate Price 2026
Nickel Alloy 625 Plate Price 2026
In 2026, the global market price for Nickel Alloy 625 (Inconel 625) plate typically ranges from $28 to $58 per kilogram (£21 to £43 per kilogram). Actual costs vary significantly depending on plate thickness, surface finish, and the form of procurement (standard mill specifications or custom-cut pieces).
Is Inconel 625 Titanium?
Differences Between Inconel 625 and Titanium
Inconel 625 has a higher melting point than titanium, allowing it to withstand higher temperatures without deforming. This makes it an ideal material for exhaust systems, turbochargers, and other components exposed to extreme heat.

Factors Affecting the Price of Alloy 625 Plates
1. Alloy Composition: Alloy 625 contains expensive elements such as molybdenum (approx. 9%) and niobium (approx. 3.5%), which significantly increase production costs.
2. Market Demand: Strong demand from the oil & gas and chemical industries in 2025 has led to tighter supplies and driven up prices.
3. Certification Requirements: Plates certified to standards such as NORSOK, ASTM B443, or ASME SB-443 typically command higher prices due to the additional testing involved.
4. Surface Finish: Compared to a standard mill finish, plates with ground, pickled, or mirror finishes may incur an additional cost of 5% to 15% above the base price.
5. Plate Dimensions (Width and Length): Large-format sizes (1500 x 3000 mm or larger) increase transportation and packaging costs.
Alloy 625 Plate Weight and Estimated Cost by Size
| Size (mm) | Thickness (mm) | Weight (kg) | Estimated Price (USD) |
|---|---|---|---|
| 1000 x 2000 | 1.0 | ≈ 16 kg | 560 – 720 |
| 1200 x 2400 | 3.0 | ≈ 86 kg | 2800 – 3600 |
| 1500 x 3000 | 5.0 | ≈ 180 kg | 5700 – 7200 |
Procurement Recommendations for Nickel Alloy 625 Plate
• Verify Alloy Certification: Ensure the plate complies with ASTM B443 or equivalent standards, and request a Material Test Certificate (MTC).
• Bulk Purchasing: Orders exceeding 500 kg typically qualify for a 5%–10% discount off factory-level pricing.
• Select Standard Sizes: Opting for standard widths-such as 1000, 1200, or 1500 mm-avoids the surcharges associated with custom rolling.
• Consider Origin: Chinese mills offer the lowest prices, whereas US and European suppliers provide stricter certification standards.

FAQ
Q：What is the unit price of Alloy 625 plate in 2026?
A：In 2026, the price of Alloy 625 nickel alloy plate ranges from $30 to $45 per kilogram, depending on the region, thickness, and surface finish.
Q：Why is Alloy 625 more expensive than other nickel plates?
A：Due to the inclusion of molybdenum (Mo) and niobium (Nb), Alloy 625 offers superior high-temperature and corrosion resistance, resulting in a higher cost compared to pure nickel plate.
Q：Where can certified Alloy 625 plate be purchased?
A：You can purchase certified Alloy 625 plate from manufacturers in the United States, Germany, China, and India. It is recommended to choose suppliers that meet ASTM B443, ASME, or NORSOK standards.
