Inconel 718 Pipe Features Include:

• High-temperature resistance: Inconel 718 pipe can withstand temperatures from cryogenic to approximately 1300°C (2372°F) without significant loss of mechanical properties.
• Corrosion resistance: The composition of Inconel 2.4668 includes elements such as chromium, molybdenum, and niobium, which make it have excellent corrosion resistance. This feature is especially important in environments where there is constant exposure to harsh chemicals or corrosive gases.
• High strength: Inconel 718 material has high tensile strength and yield strength, the tensile strength is 1,35,000 psi 930 MPa, and the yield strength is 75,000 psi 482 MPa. This enables the In718 pipe to withstand high pressure and stress.
• Fatigue resistance: The fatigue resistance and stress corrosion cracking resistance of Inconel alloy 718 are critical for applications involving cyclic loading such as aerospace and oil and gas industries.

 

Heat Treatment of Inconel 718 Pipe
Age hardening is a heat treatment process that can significantly increase the hardness and strength of Inconel alloy 718 if Inconel alloy 718 pipe is machined in an age-hardened condition. Inconel 718 pipe is precipitation hardened which further enhances the mechanical properties of the pipe for applications requiring high tensile and yield strengths as well as good creep rupture properties. ASME SB163 UNS N07718 seamless Ttubing shows longer tool life if produced in the annealed condition. ASTM B163 Inconel 718 seamless pipe for condensers and heat exchangers.
