Characteristics of Inconel 718
- Good mechanical properties – tensile, fatigue and creep-rupture
- Yield tensile strength, creep, and rupture strength properties are exceedingly high
- Highly resistant to chloride and sulfide stress corrosion cracking
- Resistant to aqueous corrosion and chloride ion stress corrosion cracking
- High temperature resistant
- Age-hardenable with a unique property of slow aging response that permits heating and cooling during annealing without the danger of cracking.
- Excellent welding characteristics, resistant to postweld age cracking
