Inconel 718 is a vacuum melting (double or triple melting to keep clean) precipitation hardening nickel alloy.
It retains its high strength, resistance to oxidation, and corrosion, while maintaining its superior ductility in extreme environments. Inconel 718 is used in critical applications in many industries, including aerospace, defense, and petrochemical. Inconel 718 features excellent tensile, fatigue, creep and breaking strength at temperatures up to 1290 °F (980 °C). This makes it ideal for many high-temperature applications, such as gas turbines, instrumentation, and power process industry parts. It also has excellent practicality for low-temperature applications. Parts made of Inconel 718 can be easily post-hardened by precipitation hardening heat treatment. In both conventional and age-hardened states, parts can be machined, spark etched, welded, micro-peened, polished, and coated if required.
Inconel 718 alloy has good mechanical properties such as high strength, high tensile properties, high fatigue life and high creep rupture strength. These mechanical properties make Inconel 718 alloy widely used in the aerospace, chemical, petroleum and nuclear industries.
Inconel 718 alloy is an ultra-heat-resistant nickel-based alloy that is able to work stably for long periods of time at high temperatures. It has a wide operating temperature range and can typically be used in temperatures as low as -253°C to as high as 704°C. In addition, Inconel 718 alloy has good oxidation and corrosion resistance at high temperatures, making it one of the ideal materials for many high-temperature applications.
