In Fastners LLP, we manufacture and distribute high-end Inconel 718 fasteners specifically designed to meet the stringent specifications of crucial industrial applications across the globe. We will explore the characteristics of Inconel 718 fasteners, the most important properties they possess, application, as well as performance advantages.
What Are Inconel 718 Fasteners?
Inconel 718 Fasteners are fastening components manufactured from Inconel 718, a nickel-chromium-based superalloy known for its outstanding mechanical properties and resistance to extreme environments. It is a mixture of iron, nickel, chromium molybdenum and niobium. Aluminum, titanium which creates a unique mix of strength and resistance to corrosion.
These fasteners come in many forms, such as:
- Bolts
- Nuts
- Screws
- Washers
- Stud Bolts
- Threaded Rods
- Anchor Fasteners
Of the many, Inconel 718 bolts are especially sought-after due to their ability to ensure structural integrity even when pressure is high and temperatures.
Chemical Composition of Inconel 718
The outstanding efficiency of Inconel 718 is due to its chemical composition that is carefully balanced:
- Nickel (50-55%)
- Chromium (17-21%)
- Iron (Balance)
- Niobium (4.75-5.5%)
- Molybdenum (2.8-3.3%)
- Titanium (0.65-1.15%)
- Aluminum (0.2-0.8%)
This formulation allows precipitation hardening that significantly increases the durability and strength of the product.
Key Properties of Inconel 718 Fasteners
1. Exceptional High-Temperature Strength
One of the main features that distinguishes Inconel 718 fasteners is their capacity to maintain high tensile and yield strength even at temperatures of 700 degrees Celsius and above. Contrary to traditional stainless steel fasteners, these are not affected by mechanical instability when exposed to heat for long periods of time.
2. Superior Corrosion Resistance
Inconel 718 has excellent resistance to:
- Oxidation
- Chloride-induced corrosion
- Sulfidation
- Pitting corrosion
- Crevice corrosion
This is what makes Inconel 718 bolts perfect to be used on offshore structures, chemicals plants and marine environments.
3. Outstanding Fatigue Resistance
Industrial equipment is often subject to high-frequency vibration and cyclic load. Inconel 718 offers the highest strength for fatigue, and guarantees the longest service life, even with stress variations.
4. Excellent Creep Resistance
At high temperatures, many substances deform because of creep. Inconel 718 fasteners provide an exceptional resistance to creep deformation which makes them ideal for turbine engines as well as high temperature processing equipment.
5. High Mechanical Strength
The alloy is extremely strong in yield and tensile strength when in comparison to traditional fastening material. This allows engineers to utilize smaller fasteners, without compromising their performance.
6. Good Weldability
Contrary to some alloys with high strength, Inconel 718 is a great weldable alloy with excellent fabrication capabilities which makes it easy to incorporate into complicated assemblies.
