Inconel 625 vs 718 Scrap — Which Grade Is Worth More?
Published by InconelScrap.com | Updated June 2026
Inconel 625 and Inconel 718 are the two most commonly traded nickel superalloy scrap grades. Both command premium prices, but they differ significantly in composition, applications, and scrap value. Here's everything you need to know.
Quick Comparison
| Property | Inconel 625 | Inconel 718 |
|---|---|---|
| Nickel Content | 58–63% | 50–55% |
| Key Alloying Elements | Cr, Mo, Nb | Cr, Nb, Fe, Mo |
| Scrap Price Range | $8.50–$12.00/lb | $9.00–$13.50/lb |
| Primary Applications | Marine, chemical, oil & gas | Aerospace, gas turbines |
| Strength Level | Medium-high | Very high (age-hardenable) |
| Weldability | Excellent | Good |
Why Inconel 718 Typically Prices Higher
Inconel 718 generally commands a slight premium over 625 for several reasons:
Aerospace demand: 718 is the workhorse of the aerospace industry, used in jet engine discs, rings, casings, and fasteners. Aerospace remelters pay a premium for identified 718 scrap.
Higher niobium content: 718 contains ~5% niobium (columbium), which is a high-value alloying element that adds to the scrap value.
Tighter supply: 718 is produced in smaller quantities than 625, and most 718 scrap is generated by aerospace machining operations rather than general industrial use.
When 625 Can Price Higher
In certain market conditions, 625 can match or exceed 718 pricing:
Large clean lots: A large, clean, segregated lot of 625 bar or plate can attract aggressive bids from chemical plant and oil & gas equipment manufacturers.
Weld overlay applications: 625 is widely used for weld overlay (cladding) in the oil & gas industry. Surplus 625 welding wire commands very high prices.
Bottom Line
Both grades are valuable. The most important thing is to keep them segregated — mixing 625 and 718 will result in both being priced as a mixed lot at a significant discount. Call Sean at 954-488-0700 for current pricing on your specific material.
