Why Aerospace Engineers Choose Our Inconel Fasteners
1. Superior High-Temperature Strength
Turbine engines and exhaust systems operate at temperatures exceeding 1000°F. Inconel 718 and 625 maintain their mechanical properties where titanium and stainless steel fail.
2. Fatigue Resistance
Our precision-rolled threads eliminate stress risers, significantly improving fatigue life under dynamic loading conditions—critical for airframe and engine applications.
3. Corrosion Protection
Resistance to jet fuel, hydraulic fluids, and atmospheric corrosion ensures long-term reliability in harsh operating environments.
4. Full Traceability
Each lot is accompanied by complete material certifications, heat lot traceability, and conformance to AMS, ASTM, and customer-specific specifications
Understanding Inconel Grades
| Grade | Composition Highlights | Key Strengths | Ideal Applications |
|---|---|---|---|
| 600 | Ni 72%, Cr 15% | Oxidation resistance, high-temperature strength | Furnace components, heat treat fixtures |
| 625 | Ni 61%, Cr 21%, Mo 9% | Fatigue resistance, pitting corrosion | Marine hardware, chemical processing |
| 718 | Ni 53%, Cr 18%, Nb 5% | Age-hardenable, highest tensile strength | Aerospace engines, gas turbines |
| 825 | Ni 42%, Cr 21%, Mo 3% | Acid resistance, stress corrosion cracking | Oil & gas downhole, pickling equipment |
When to Specify Inconel Fasteners
✅ Operating temperatures exceed 800°F (425°C)
✅ Exposure to seawater, chlorides, or acidic environments
✅ Cyclical loading requiring high fatigue resistance
✅ Stress corrosion cracking is a concern
✅ Component failure is not an option
