Product Overview and Material Composition
Inconel 718 is a precipitation-hardenable nickel-based superalloy developed to provide outstanding tensile strength, fatigue resistance, creep resistance, and oxidation resistance at elevated temperatures. The alloy derives its superior performance from carefully controlled additions of chromium, niobium, molybdenum, titanium, and aluminum.
The typical chemical composition includes approximately 50–55% nickel, 17–21% chromium, 4.75–5.50% niobium, 2.8–3.3% molybdenum, and smaller quantities of titanium and aluminum. This balanced composition enables the formation of strengthening phases that significantly enhance the mechanical performance of the alloy.
The high nickel content provides exceptional resistance to chloride stress corrosion cracking, while chromium contributes to oxidation and corrosion resistance. Niobium and molybdenum enhance strength and stability under high-temperature conditions, making Inconel 718 Fasteners a preferred choice for critical engineering applications.
Mechanical Properties and Performance Characteristics
One of the primary reasons industries choose Inconel 718 Fasteners is their remarkable mechanical strength. These fasteners maintain excellent structural integrity even under severe thermal and mechanical stresses.
Typical mechanical properties include:
- High tensile strength
- Excellent yield strength
- Superior fatigue resistance
- Outstanding creep rupture resistance
- Excellent fracture toughness
- High impact resistance
The precipitation-hardening process significantly increases the strength of the material without compromising ductility. As a result, Inconel 718 Fasteners perform exceptionally well in applications involving cyclic loading, vibration, and thermal expansion.
The alloy retains its mechanical properties across a wide temperature range, making it suitable for cryogenic as well as high-temperature service conditions.
Chemical Properties and Corrosion Resistance
The corrosion resistance of Inconel 718 Fasteners is one of their most valuable characteristics. The alloy performs exceptionally well in oxidizing and reducing environments, offering protection against various forms of corrosion.
These fasteners demonstrate excellent resistance to:
