Both the Inconel 718 strip and the Inconel X-750 strip belong to the nickel superalloys strips, showcasing impressive attributes like exceptional corrosion resistance, robust strength, and remarkable heat tolerance.
These qualities set them apart from solid solution alloys, a distinction frequently discussed in accessible online articles covering their differences.
Nevertheless, in terms of comparing Inconel 718 and Inconel X-750 alloys strips, there’s a scarcity of comprehensive references available.
Within this blog article, we will thoroughly contrast these two alloys strips by delving into their chemical compositions, applications, and overall performance.
Let’s keep reading.
What is Inconel 718 Alloy Strip?
Inconel 718 alloy strip is a high-strength, corrosion-resistant nickel chromium strip material used at -423° to 1300°F temperature.
The age-hardenable alloy strip can be readily fabricated, even into complex end finished parts. Its welding characteristics, especially its resistance to postweld cracking, are outstanding.
Inconel 718 strips are slitted from mother coils.

| Grade | Standard | C | Si | Mn | P | S | Cr | Ni | Ti |
| Inconel 718 | ASTM B 670, ASTM B 906, SAE AMS 5596 | ≤0.08 | ≤0.35 | ≤0.35 | ≤0.015 | ≤0.015 | 17.00-21.00 | 50.0-55.0 | 0.65-1.15 |
Inconel X-750 Alloy Strip Chemical Composition
| Grade | Standard | C | Si | Mn | P | S | Cr | Ni | Ti |
| Inconel X-750 | AMS 5542 | ≤0.08 | ≤0.50 | ≤1.00 | ≤0.015 | ≤0.010 | 14.00-17.00 | ≥70 | 2.25-2.75 |
Corrosion Resistance
In comparison to Inconel X-750 strip, Inconel 718 strip possesses a higher chromium content.
As a result, Inconel 718 exhibits enhanced oxidation resistance when compared to Inconel X-750.
Furthermore, Alloy 718 includes molybdenum, a component absent in Alloy X-750. The incorporation of molybdenum serves to enhance the reduction corrosion resistance of Inconel 718.
Consequently, Inconel 718 strip outperforms Inconel X-750 strip across all facets of corrosion resistance.

Price
While Inconel X-750 strip lags behind Inconel 718 strip in most aspects, the price discrepancy between them isn’t significantly substantial.
This can be attributed to Inconel 718’s lower nickel content and elevated iron content. These factors contribute to a reduction in the raw material expenses for the alloy.
Simultaneously, the widespread utilization of Inconel 718 results in a substantial supply, thereby lowering its incremental cost.
As a result, if your project is confronted with the decision between these two materials, our suggestion is to prioritize Inconel 718 strip. It not only boasts superior performance but also comes at an equivalent cost.
Conclusion
In summary, the Inconel 718 strip surpasses X-750 alloy strip in terms of overall performance. This is primarily due to its higher tensile strength both at room temperature and elevated temperatures.
