Inconel 718 Tubing

INCONEL 718 Tubing stands out as an corrosion resistant material made of nickel and chromium. Its unique chemical composition includes elements like niobium, titanium and molybdenum combined with an amount of nickel, chromium and a small portion of iron. This specific blend not allows for welding but also boosts its strength through the age hardening process.


When it comes to performance INCONEL 718 Tubing boasts qualities, such as its ability to withstand environmental conditions. It can endure temperatures ranging from 423°F ( 253°C) to high as 1300°F (705°C) without compromising its integrity. This versatility in handling temperature ranges sets it apart from other materials in its category. Particularly in temperature and high stress environments where many other tubings may be prone to cracking after welding.


Regarding its characteristics Inconel 718 Ams 5589 showcases yield strength, tensile strength and creep rupture properties at elevated temperatures. It also demonstrates fatigue resistance. Remains ductile even under low temperature conditions. Additionally cold work can significantly increase its hardness level while maintaining durability.


With these characteristics in mind 2.4668 Tubing is highly recommended for a variety of industries and applications. These include the manufacturing of gas turbine engine components, cryogenic storage tanks, rocket propulsion systems, nuclear reactors and valve parts. Its capacity to endure stress and temperatures makes it ideal for use in oil extraction and gas drilling activities in environments rich in hydrogen sulfide. Additionally its resistance to corrosion coupled with its strength at elevated temperatures makes it an excellent choice for chemical processing tasks. From aerospace engineering to energy generation sectors, the versatility of Inconel 718 Bright Annealed Tube ensures its ranging utility across industries.
