Inconel 718 application areas depend on its hot strength, excellent corrosion resistance and workability at 700 C. Inconel 718 can be widely used in a variety of highly demanding occasions:
1. steam turbine
2. liquid-fuel rocket
3. Cryogenic engineering
4. Acid environment
5. Nuclear engineering
Other properties of Inconel 718:
1. at 700 C, it has high tensile strength, fatigue resistance, creep  resistance and fracture resistant strength
2. It has high oxidation resistance at 1000 C. Inconel 718 nickel alloy has especial outstanding oxidation resistance at high temperature. In both high temperature and low temperature environment, Inconel 718 nickel alloy has excellent resistance to stress corrosion cracking and pitting corrosion.
3. It has stable chemical properties at low temperatures.
4. Excellent welding performance, it can be welded by argon arc welding, electron beam welding, slit bonding, spot welding and other welding methods.
