INCONEL® is a trademark of the Special Metals Corporation group of companies. stream • Commonly referred to as Inconel® 718 Alloy 718 is a high strength, corrosion resistant nickel chromium alloy, initially developed for the aerospace industry and still considered the material of choice for the majority of aircraft engine components. Inconel® 718 is an age-hardenable Nickel-Chromium-Columbium (Niobium)-Molybdenum alloy with high strength, corrosion- resistance, and good fabrication characteristics. Inconel 718 alloy is widely considered as one of the candidate materials suitable for application at temperatures below 650oC. Engineers are constantly looking to improve the reliability and efficiency of engines, not to mention their longevity. Alloy 718 is a precipitation hardenable nickel-based alloy designed to display exceptionally high yield, tensile and creep-rupture properties at temperatures up to 1300°F. Inconel 718 is a precipitation-hardenable nickel-chromium alloy containing significant amounts of iron, niobium, and molybdenum along with lesser amounts of aluminum and titanium.
