What are the features of Nickel-based superalloy 718

Alloy 718 (UNS N07718, W Nr 2.4668) is an austenitic nickel-based superalloy. Alloy 718 exhibits excellent high yield tensile and creep-rupture properties at temperatures up to 1300ºF and oxidation resistance to 1800ºF. Alloy 718 is used in applications that require high strength such as parts for jet engines and high speed airframe parts such as wheels, buckets, spacers and high temperature bolts and fasteners.

Nickel-based superalloy 718 has the following characteristics:
1. Ease of processing;
2. It has high tensile strength, fatigue strength, creep strength and breaking strength at 700℃;
3. It has high oxidation resistance at 1000°C;
4. Has stable chemical properties at low temperatures;
5. Good welding performance.
