GH4169/UNS N07718: A Premier Precipitation-Strengthened Nickel-Based Superalloy

​GH4169, also known as UNS N07718, is a precipitation-strengthened nickel-based superalloy that exhibits exceptional performance under extreme temperatures. This alloy's chemical composition primarily comprises nickel, with additions of chromium, iron, cobalt, molybdenum, and aluminum. These elements contribute to GH4169's remarkable strength, corrosion resistance, and high-temperature stability.
The impact temperature of GH4169 ranges from cryogenic temperatures up to 980°C (1800°F), making it suitable for use in both high- and low-temperature environments. Its mechanical properties, including tensile strength, yield strength, and elongation, are superior to those of other alloys, making it a preferred material for critical applications.
The heat treatment of GH4169 is crucial to achieve its optimal mechanical properties. The alloy is typically solution treated at high temperatures, followed by rapid cooling to retain the desired microstructure. This is followed by precipitation hardening treatments, where the aluminum and titanium components form strengthening precipitates within the nickel matrix.
GH4169 is available in a wide range of sizes and shapes, including sheets, plates, bars, and wires, to cater to different industrial requirements. Its primary applications are in the aerospace, energy, and chemical processing industries, where it finds use in components exposed to extreme temperatures and corrosive environments.
