3D printing Inconel: For high-temperature applications

Inconel is the generic term for various nickel-based superalloys from the manufacturer Special Metal Corporation. In addition to nickel, these superalloys also contain chromium, magnesium, iron and titanium in varying proportions. 3D printing Inconel is a heat-resistant or high-temperature alloy.

Which 3D printing Inconel material is the best choice?
Due to its excellent production performance and proven material properties, we work with the most widely used Inconel material, IN718, for 3D printing. The nickel-chromium alloy IN718 consists of 50 to 55% nickel, 17 to 21% chromium and twelve other metals with smaller proportions. 3D printing Inconel is ideal for the additive manufacturing of products for high-temperature applications and other extreme requirements, such as engine parts, turbines or heat exchange and piping systems.

This material property of 3D printing Inconel is convincing
In additive manufacturing, powdered 3D printing Inconel 718 is used for components that are exposed to extreme environmental conditions and high mechanical loads. In addition, 3D printing Inconel 718 is always a good choice when the workpieces need to be resistant to corrosion and oxidation.

Advantages of 3D printing Inconel 718

  • Very high temperature resistance
  • Very good corrosion and oxidation resistance
  • Suitable for cryogenic environments
  • Homogeneous and dense surface structure
  • High tensile and elongation strength
  • Good creep and fracture resistance
  • More cost-effective in 3D printing than in machining

Fields of application for 3D printing Inconel 718:
The powdered Inconel material IN 718 is ideal for the cost-effective 3D printing of components with intricate designs, very thin walls or internal structures. These workpieces are used in the aerospace and motorsport industries, among others. 3D printing Inconel 718 is an excellent replacement for aluminum and steel when creep problems are expected under extreme environmental conditions.

Nickel-chromium alloy for all extremes

The superalloy Inconel 718 was originally developed specifically for the manufacture of jet engines. It had to be strong, heat- and corrosion-resistant, but also lightweight and cost-effective. Today, Inconel 718 is the most widely used superalloy in the world because it can be used in extreme environmental conditions without any problems over the long term. 3D printing Inconel 718 is extremely heat-resistant and strong up to a temperature of 700 °C because the material builds up a thick protective layer of chromium oxide and prevents corrosion and oxidation. In addition, 3D printing Inconel 718 is characterized by good tensile and elongation strength as well as good elongation at break properties and can also withstand very low kyrogenic temperatures.
