Inconel 718 bolts offer numerous advantages, primarily due to their exceptional high-temperature strength and corrosion resistance. They maintain their mechanical properties under high stress and elevated temperatures, making them ideal for demanding applications such as aerospace and chemical processing. Furthermore, their resistance to oxidation and various corrosive media, including acids and salt water, further expands their usefulness in harsh environments.
At what temperature does Inconel 718 oxidize?
Inconel 718 oxidizes at a parabolic, diffusion-controlled rate over a wide temperature range of 1223 K to 1573 K in atmospheric air, lasting for weeks. Above 1573 K, oxidation becomes extremely intense, causing severe deformation.

Advantages of Inconel 718 Bolts
Inconel 718 is an age-hardenable nickel-chromium alloy that combines corrosion resistance with high strength and good machinability. It exhibits high creep rupture strength at temperatures up to 700°C.
UNS N07718 bolts are precipitation hardenable and can be heat treated to achieve higher strength than wrought nickel-chromium alloys and some other cast nickel-base superalloys.
The high strength of UNS N07718 bolts makes them suitable for many demanding applications, such as those in the aerospace, oil and gas, and power generation industries.
UNS N07718 bolts, which conform to ASTM B637, also withstand a wide range of corrosive environments, making them an ideal choice for marine and chemical processing applications.
The numerous advantages of UNS N07718 bolts make them a popular choice for a wide range of industries and applications.
