Inconel 625 seamless pipes are highly sought after for use in extreme environments due to their excellent strength, corrosion resistance, and thermal stability. They are primarily used in chemical processing, power generation, marine, and aerospace applications. As of 2025, the price of Inconel 625 seamless pipe has remained elevated due to high raw material costs, energy prices, and supply chain constraints. Below is a detailed breakdown of the pricing, influencing factors, and reliable global manufacturers.
Inconel 625 Seamless Pipe Price by Size (2025)
| Pipe Size (OD) | Wall Thickness | Standard | Price Range (USD per Meter) |
|---|---|---|---|
| 1/2” (12.7mm) | 1.5mm | ASTM B444 | $150 – $220 |
| 1” (25.4mm) | 2.0mm | ASTM B444 | $180 – $260 |
| 2” (50.8mm) | 3.0mm | ASTM B444 | $230 – $330 |
| 4” (101.6mm) | 4.5mm | ASTM B444 | $280 – $400 |
| 6” (152.4mm) | 6.0mm | ASTM B444 | $350 – $500 |
Inconel 625 Pipe Price Per Kg and Per Pound
| Unit | Low-End Price | High-End Price |
|---|---|---|
| USD / kg | $44 | $84 |
| USD / lb | $20 | $38 |
Seamless pipes are priced higher than flat products like sheets due to complex manufacturing processes such as extrusion or rotary piercing.
Key Factors Influencing Seamless Pipe Price
• Nickel and Molybdenum Costs: Inconel 625 contains over 58% nickel and 8–10% molybdenum, which are expensive and volatile metals.
• Pipe Size and Wall Thickness: Larger OD and thicker walls significantly increase price due to more raw material and machining time.
• Manufacturing Standard: Pipes certified to ASTM B444, NACE MR0175, or ASME standards cost more due to tighter tolerances and testing.
• Supply Chain Origin: Pipes from the USA and EU are more expensive than those from China or India, due to higher labor and regulatory compliance costs.
