- Custom sizes available upon request
These products are extensively paired with Inconel 625 bolts, studs, threaded rods, and other high-performance fastening systems.
Material Composition and Chemical Properties
The exceptional durability of Inconel 625 Nuts originates from their carefully balanced chemical composition. Nickel forms the base of the alloy, providing excellent resistance to reducing environments, while chromium creates a protective oxide layer that improves oxidation resistance. Molybdenum significantly enhances resistance against localized corrosion such as pitting and crevice corrosion, whereas niobium increases mechanical strength through solid-solution strengthening.
Typical Chemical Composition
| Element | Percentage |
|---|---|
| Nickel (Ni) | 58% Minimum |
| Chromium (Cr) | 20.0–23.0% |
| Molybdenum (Mo) | 8.0–10.0% |
| Niobium + Tantalum | 3.15–4.15% |
| Iron (Fe) | 5.0% Maximum |
| Cobalt (Co) | 1.0% Maximum |
| Aluminum | 0.40% Maximum |
| Titanium | 0.40% Maximum |
| Carbon | 0.10% Maximum |
| Manganese | 0.50% Maximum |
| Silicon | 0.50% Maximum |
| Phosphorus | 0.015% Maximum |
| Sulfur | 0.015% Maximum |
This composition allows the alloy to perform exceptionally well in acidic media, chloride-rich environments, oxidizing chemicals, and seawater exposure.
Mechanical Properties of Inconel 625 Nuts
Mechanical reliability is one of the strongest advantages of Inconel 625 Nuts. The alloy retains impressive tensile strength while resisting deformation under high-pressure and elevated-temperature conditions.
