Everything You Need to Know About Inconel 718 Bolts

Inconel 718 bolts are a staple in industries that demand high performance and durability under extreme conditions. These bolts are part of the larger family of Inconel alloys, which are nickel-chromium-based superalloys known for their excellent corrosion resistance, high strength, and stability at high temperatures. This blog will delve into the unique properties, applications, and benefits of Inconel 718 bolts.

What is Inconel 718?

Inconel 718 is a precipitation-hardenable nickel-chromium alloy containing significant amounts of iron, niobium, and molybdenum, along with smaller amounts of aluminum and titanium. It was developed to provide exceptional strength and corrosion resistance, particularly in harsh environments. The alloy is known for its ability to withstand high stress and a wide range of temperatures, making it ideal for a variety of applications.

Key Properties of Inconel 718

1. High Strength and Durability: Inconel 750 maintains high tensile, yield, and creep-rupture properties, even at temperatures up to 1300°F (704°C). The precipitation hardening process further enhances its strength.
2. Corrosion Resistance: The alloy is highly resistant to oxidation and corrosion in a wide range of environments, including marine and acidic conditions.
3. Temperature Stability: Inconel 718 can withstand both cryogenic temperatures and high temperatures up to 1300°F (704°C) without losing its structural integrity.
4. Fatigue Resistance: The alloy’s superior fatigue resistance makes it suitable for applications involving cyclic loads.
5. Weldability: Unlike many other high-strength alloys, Inconel 718 can be welded easily and retains its mechanical properties after welding.
