Inconel 718 Pipe

What is Inconel 718 pipe?

Inconel superalloy with nickel base has revolutionized the piping industry with enormous strength and high heat temperature of up to 2000 F. Inconel 718 pipe is made from superalloy with unique composition, makes it ideal for use to engineering components even for liquid-fuelled rockets.

Inconel 718 seamless pipe has nickel 50 to 55%, chromium 17 – 21%, iron nominal 18.5%, molybdenum 7 – 9.5%, niobium 2.75 to 4 %, and titanium 1 – 1.75%. There are also many other elements with less than a percent to make UNS N07718 pipe. It includes sulfur, manganese, carbon-silicon, phosphorous, and boron.

Inconel 718 Pipe Properties

Inconel 718 seamless pipe advantages and disadvantages

Inconel 718 seamless pipe because of its unique composition, has many advantages and disadvantages that include the following.

  • Has high strength and corrosion resistance to be useful in applications with a temperature range from minus 423 to 1300 Fahrenheit.
  • Made from age or precipitation hardenable alloy, it is easy to fabricate even into complex parts
  • Has excellent welding properties without cracking
  • Have the best mechanical properties of tensile & yield strength, fatigue & creep rupture, etc
  • Offer high resistance to corrosion, chloride,
  • Hae sulfide stress corrosion cracking.
  • Best for many high-temperature applications like use in rockets, rings, casings, and others

The significant disadvantage of Inconel 718 pipe is its susceptibility to metallurgical problems during welding. It includes problems like HAZ liquation cracking and laves phase formation in FZ or fusion zone.

What are Inconel 718 pipe annealed properties?

Annealing properties are critical for alloys to increase elasticity to decrease their hardness to work efficiently. 718 pipes has the best-annealed properties to withstand even 1300 degrees Fahrenheit. As an age-hardenable alloy with no major detrimental effects is easy to anneal and weld with no need for spontaneous hardening to heat or cool.

The WNR 2.4668 pipe increases its strength at room temperature by the heat precipitation method. Hence it is suitable for applications even in extreme environments. As per the end-user, Inconel 718 pipes need different annealing solutions to have high tensile and stress-rupture properties.

Inconel 718 vs. 625 seamless pipe

Seamless pipes with no seams or joints are ideal for transporting water to oil, gas, and others. Hence it needs to be strong, and no other than the 718 seamless pipe has enough strength and other properties for many applications. Though Inconel 718 and 625 have many common properties like high strength, weldability, etc., there are also many differences.

  • Alloy 718 seamless pipe has a higher melting point range of 1321 to 1393 degrees Celsius than 625
  • Nickel 718 pipe is nickel and cobalt based, whereas 625 is nickel-based.
  • UNS N07718 pipes is harder and stronger than 625 because of having cobalt
  • Inconel 625 is more corrosion-resistant than 718 because of having molybdenum

What is the alloy 718 pipes forging temperature?

Inconel 718 welded pipe and others have a wide range of forging temperatures from minus 423 to 1300 degrees Fahrenheit. Hence Nickel alloy 718 pipes can change through compression in hot or cold temperatures.

Cold forging 718 pipes harden at room temperature to increase their strength. Hot forging makes 718 products to have optimal yield strength, elasticity and low low hardness.

The top Inconel 718 pipe suppliers provide high-quality AMS 5589 material at cheaper costs with no compromise on the high quality and many properties. Hence with wide-ranging forging temperatures, 718 pipes are ideal for rockets and jet engines.

Waste is not subject to charges. Many WNR 2.4668 cold drawn pipe distributors provide cut-to-length services; see standards

What are the standards of Inconel 718 pipes?

There are many standards for pipes, including seamless, welded, annealed, ERW or electrical resistance welded, etc. It includes ASTM, American Society of Testing Materials, ASME American Society of Mechanical Engineers, and API or American Petroleum Institute.

Inconel 718, a gamma prime strengthened superalloy, has many superior mechanical properties even at elevated and cryogenic temperatures. Hence, many standards include ASTM B163, B516 specifications, and others.
