Inconel 718 pipes are widely used in various industries because of their excellent mechanical properties, high-temperature performance, and superior corrosion resistance. Inconel 718 is a nickel-based alloy developed mid-20th century for high-stress applications such as gas turbine engines, rockets, and nuclear reactors. Today ASTM B163 Inconel 718 Seamless Pipes is used in various industries, including aerospace, oil and gas, chemical processing, and power generation. In this blog post, we will closely examine the composition, physical and mechanical properties, uses, and heat treatment of AMS 5589 Alloy 718 pipes.
ASTM B163 Inconel 718 Pipes Composition
Inconel 718 pipe is a nickel-chromium alloy containing significant amounts of iron, niobium, molybdenum, and smaller amounts of aluminium and titanium. Adding niobium and molybdenum provides DIN 2.4668 Pipes with exceptional mechanical properties and high-temperature performance. The aluminium and titanium additions promote the formation of a protective oxide layer that improves the UNS N07718 pipe resistance to corrosion and oxidation.
Inconel 718 Pipes Physical Properties
Astm B163 Alloy 718 has a density of 8.19 g/cm3, a melting point of 1,313°C, and a boiling point of 2,471°C. The alloy has a high specific gravity, melting point, and thermal conductivity. 2.4668 pipe is also resistant to many alkaline and acidic environments, making it suitable for chemical processing and marine applications.

AMS 5589 Alloy 718 Seamless pipe Heat Treatment
Inconel 718 pipes can be heat-treated to improve their mechanical properties and increase their resistance to corrosion and oxidation. The most commonly used heat treatment is solution annealing, which involves heating the alloy 2.4668 to a temperature of 980-1,050°C and holding it at that temperature for a specific time before cooling it in air. This process helps to dissolve any carbides and strengthen the AMS 5589 pipe grain structure.
AMS 5589 Welded pipe Corrosion Resistance
DIN 2.4668 Pipes have excellent corrosion resistance, particularly in high-temperature and corrosive environments. The Alloy 718 Pipe resistance to oxidation and pitting makes it a popular choice for harsh chemical processing and oil and gas applications. The protective oxide layer that forms on the alloy’s surface helps prevent further corrosion and extend the life of the pipe.
