Characteristics of Nickel 718
- Good mechanical properties – tensile, fatigue and variable fracture
- Yield tensile strength, creep and fracture strength properties are very high
- Highly resistant to chloride and liu compound stress corrosion cracking
- Resistance to water corrosion and chloride ion stress corrosion cracking
- High temperature resistance
- Age hardening properties, unique properties with a slow aging response, can be heated and cooled during annealing without the risk of cracking
