Functions and Uses of Inconel 718 Tubes

Inconel 718 tubes

Inconel 718 tubes are one of the preferable materials when it comes to high-temperature applications. Its impressive strength, temperature resistance, and durability make it an ideal material for use in the aerospace, engineering, and manufacturing industries. In this blog post, we will explore the various functions and uses of Inconel 718 tubes.

What are Inconel 718 tubes?

Inconel 718 is a nickel-chromium-based alloy known for its high strength and corrosion resistance, making it an ideal material for tube production. It features a chromium content of 50%, nickel content of between 18 and 21%, columbium (niobium) additions up to 7%, trace amounts of molybdenum and aluminium, and niobium carbide inclusions that form during welding. This combination of metal elements provides Inconel 718 with excellent tensile strength and good oxidation resistance at elevated temperatures, making it suitable for use in extreme environments. Additionally, Inconel 718 tubes boast high fatigue strengths, making them an effective choice for components subjected to cyclic loading over long periods. All these benefits make Inconel 718 tubes perfect for many challenging industrial applications, such as the aerospace industry, chemical processing plants, and pressure vessels in the oil & gas industry.

Uses of Inconel 718 Tubes

High-performance alloys

Inconel 718 tubes are high-performance alloys, making them resistant to high temperatures and corrosion. This property makes them ideal for gas turbines, jet engines, and diesel engines. The tubes are suitable for harsh environments where other materials melt or corrode. They can also withstand extreme pressure and have excellent mechanical properties.

Aerospace Industry

Inconel 718 tubes are an essential material in the aerospace industry. They are used in manufacturing aero plane engine components, such as turbine blades and combustors. The tubes are also used in spacecraft applications due to their outstanding thermal shock resistance, which enables them to withstand high heat and cold conditions. Additionally, Inconel 718 tubes are used in rocket engine thrust chambers, gas turbine engines, and missile propulsions.

Chemical Processing Industry

The chemical processing industry requires materials that withstand corrosion, high temperatures, and pressure. Inconel 718 tubes are corrosion-resistant and highly resistant to extreme heat and pressure, making them an ideal choice for chemical processing applications. The tubes are used in producing petroleum processing, pharmaceutical manufacturing, and other industrial processes that involve high-temperature and high-pressure corrosive environments.

Inconel 718 is a nickel-based alloy used for tubes in the chemical processing industry. This material combines high strength with excellent corrosion resistance, making it an ideal choice for applications such as sour gas pipelines, tanks and vessels containing hazardous or corrosive fluids, process piping in power plants and petrochemical production plants. Inconel 718 offers superior fatigue strength and creep rupture properties compared to comparable alloys. It can also be machined into complex shapes under extreme temperatures thanks to its weld ability. In addition, our tubes offer greater dimensional accuracy and improved surface finish when processed as cold-drawn seamless tubing providing higher performance in corrosive applications than classic carbon steel or stainless steel materials.

Medical Applications

Inconel 718 tubes are also used in medical applications such as implantable devices, metal hip prostheses, and dental implants. The tubes are highly biocompatible and resist corrosion, which ensures the longevity of implants without posing a risk to patients.

Automotive Industry

The automotive industry requires materials that withstand high stress, corrosion, and heat. Inconel 718 tubes are used in the automotive industry for manufacturing exhaust systems with the appropriate strength and corrosion-resistant properties. The tubes can handle high exhaust gas temperatures, making them suitable for high-performance cars, heavy-duty trucks, and other related applications.


Inconel 718 tubes are perfect for high-temperature applications due to their exceptional properties. Various industries like aerospace, automotive, chemical processing, and medical applications utilize Inconel 718 tubes. They have excellent mechanical and thermal properties and high corrosion and wear resistance.
