Inconel 718 Pipe and ASTM B163 UNS N07718 Seamless tube

Inconel 718 is an age-hardenable Nickel-Chromium-Columbium (Niobium)-Molybdenum alloy with excellent corrosion resistant properties. It is a high strength alloy that is compatible in both high and low-temperature environments (-423 F - 1300 F) (253 C - 704 C). It exhibits excellent fatigue, creep, and rupture strength making it an ideal alloy for fabricating springs. It is a superior material choice to Inconel X750 at higher temperatures when material strength is a factor.

Wide Range of Operating Environments 
The alloy retains 75% of its tensile strength up to 1300 F (704 C). Inconel 718 remains ductile in cryogenic environments and is suitable for low-temperature applications like compressed liquid natural gas or CO2 processing. It retains 85% of its ductility at temperatures down to -400 F (-240 C). 718 also performs better than Nimonic 90 at cryogenic temperatures. The material performs well in sour gas environments although there are other nickel alloys such as Inconel 625 and Inconel 725 that perform even better.

Inconel 718 Heat Treatment Specifications 
Inconel 718 is also resistant to hydrogen embrittlement and stress corrosion cracking with HRc values as high as 40 when in the solution annealed and aged condition. To meet these requirements the NACE MR1075 specifications for heat treatment are followed. The material is typically solution annealed at 1850-1900 F (1010 - 1040 C) and precipitation hardened at 1450 F (780 C) up to 8 hrs.

High Fatigue & Material Strength
To meet high fatigue and material strength, heat treatment is conducted by solution annealing at 1700 - 1800 F (925 - 980 C) followed by a rapid cool and precipitation hardening at 1325 F (720 C) for 8 hrs. and furnace cooling to 1150 F (620 C) for 18 hours.
