718 Inconel Round Bar​

Inconel 718 Round Bar is a high-strength, corrosion-resistant nickel-chromium alloy designed for applications where high-temperature strength and oxidation resistance are crucial. It is commonly used in industries such as aerospace, gas turbines, and chemical processing, where parts are exposed to extreme environments.

Key Features of Inconel 718 Round Bar:

Composition:

Nickel (Ni): 50-55%

Chromium (Cr): 17-21%

Iron (Fe): Balance

Molybdenum (Mo): 2.8-3.3%

Titanium (Ti): 0.65-1.15%

Aluminum (Al): 0.2-0.8%

Niobium (Nb): 4.75-5.5%

Cobalt (Co): 1-2.5%

Strength and Durability:

Excellent high-temperature strength up to 704°C (1300°F).

Good creep and fatigue resistance.

Corrosion and oxidation resistance in both high and low-temperature environments.

Applications:

Aerospace: Engine components, turbine blades, and other critical structural parts.

Gas Turbines: Hot sections and components that operate in high-pressure, high-temperature environments.

Nuclear and Chemical Processing: Reactor components and equipment that require superior resistance to heat and aggressive environments.

Heat Treatment:

Solution annealing followed by age hardening to enhance mechanical properties.

Weldability:

Inconel 718 is readily weldable, but special care is needed to avoid cracking due to its high strength and the risk of hot cracking.

Benefits of Inconel 718 Round Bar:

Exceptional strength-to-weight ratio: Crucial for aerospace applications.

Resistance to oxidation and corrosion: High performance in extreme temperatures.

Versatile machining: Although challenging, it can be machined using appropriate techniques.
