Inconel 625 is a premium-grade nickel-based superalloy recognized for its excellent corrosion resistance, high strength, and resistance to extreme temperatures. Due to its unique chemical composition and complex manufacturing process, the cost of Inconel 625 is significantly higher than standard stainless steels or industrial alloys. This article provides a comprehensive breakdown of the current Inconel 625 costs by form, influencing factors, and trusted suppliers in 2025.
Average Cost of Inconel 625 in 2025
| Form | Common Sizes | Cost Range (USD/KG) | Notes |
|---|---|---|---|
| Sheet / Plate | 1.0 – 10 mm thick | 45 – 65 | Available in ASTM B443 |
| Bar / Rod | 10 – 100 mm dia | 50 – 70 | ASTM B446 standard |
| Pipe / Tube | 6 – 219 mm OD | 55 – 75 | Seamless pipes are more expensive |
| Wire | 0.5 – 3.2 mm | 60 – 85 | Used for welding and springs |
Cost Comparison with Other Alloys
| Alloy | Approximate Cost (USD/KG) | Notes |
|---|---|---|
| Inconel 625 | 45 – 85 | Premium nickel alloy |
| Inconel 600 | 35 – 55 | Lower molybdenum content |
| Nickel 200 | 30 – 50 | Purer nickel, less strength |
| 304 Stainless Steel | 2.5 – 3.5 | Basic stainless alloy |
| 316L Stainless Steel | 3.5 – 5.0 | Marine-grade SS |
Major Cost Factors of Inconel 625
• Nickel Content: With about 58% nickel, price is heavily affected by LME nickel rates.
• Alloying Elements: Molybdenum, chromium, niobium also add to cost.
• Manufacturing Method: Seamless tubes, cold-rolled sheets, or precision wire increase production costs.
• Certification: Items meeting ASTM B443/B444/B446 and EN standards are priced higher.
• Origin & Logistics: Products from the US and EU are costlier than those from China or India.
