718 Alloy for Aerospace Fasteners and Turbine Components

718 Alloy is among the best-selling Nickel-Based Super Alloys within the Aerospace Industry. The alloy's excellent strength, high temperature capabilities and ability to withstand corrosive materials make it ideal for use as an aerospace fastener, turbine component and other critical aircraft engine components. Aircraft and Turbine Systems are subjected to extreme conditions including heat, pressure and mechanical stress. Therefore, for reliable, long term performance in these applications, 718 Alloy meets those demands.

718 Alloy is a precipitation hardening Nickel-Chromium alloy to be used in applications which are required of:

Because 718 Alloy's mechanical properties do not degrade with increased temperature, it is commonly utilized within the aerospace and power generation industries.

Aerospace parts experience one of the most extreme and stressful operating environments with conditions such as:

The high strength, toughness and temperature stability of 718 Alloy make it an ideal choice for aerospace applications.

Fasteners play a vital role in the construction of commercial and military aircraft as well as their engines. When failure occurs, even with fastener elements that fail at lower loads than anticipated by design, the potential for catastrophic damage exists.

Aerospace fasteners require:

718 Alloy has the necessary mechanical properties so that it can provide structural stability when exposed to such an environment.

Due to high strength and high temperature corrosion resistance, 718 Alloy has many uses within aerospace for both airframes and turbine components.

Components of a gas turbine or jet engine are subjected to extreme heat and stress. Therefore, the components in this system need to be made with a material that can withstand the loss of mechanical properties at elevated temperature conditions.

The alloy's ability to maintain mechanical stability under prolonged thermal exposure makes it ideal for these applications.

One of the most important advantages of using 718 Alloy is the ability to operate in high-temperature environments.

Benefits include:

In this way, 718 Alloy will be useful for use on aerospace engines, turbines, and exhaust systems where there are extreme temperatures involved.

Its major benefit is protecting against several types of corrosive processes which may exist at extremely high temperatures within aircraft engines or turbines.

718 Alloy provides an additional level of protection through resistance to:

Protecting components from damage resulting from these corrosive processes reduces overall downtime required for repair/maintenance.

Aerospace parts experience repeated loading and unloading cycles throughout their service life.

If the part or structure cannot withstand such cyclic loading, the eventual result will likely be a catastrophic failure of the structure due to fatigue.

Therefore, 718 Alloy has an extremely beneficial combination of mechanical characteristics, including:

Properties that are very important when considering both aerospace fasteners and rotary turbine components.

Although aerospace is the largest user of 718 Alloy, the alloy is also used in:

When it comes to working with high temperature and load conditions (like those found in aerospace), you can replace your stainless steel parts with 718 Alloy.

718 Alloy is a suitable choice when the application requires:

You may find that it has great value when building mission-critical components that require maximum performance and safety.
