Nickel-Base Superalloy
Inconel 718 (UNS Designation N07718)
Mechanical Properties
Room Temperature Properties
The room temperature strength of the Inconel 718 is substantially increased by precipitation heat treatment as the following data indicate. These values are properties specified for sheet, strip and plate in AMS 5596 and AMS 5597.
| Yield Strength Max (0.2% Offset) | Ultimate Tensile Strength Max | Elongation (% in 2") | |
|---|---|---|---|
| Sheet and Strip | 80,000 psi (550 MPa) | 14,000 (965 MPa) | 30 (min) |
| Plate | 105,000 psi (725 MPa) | 150,000 (1,035 MPa) | 30 (min) |
| Yield Strength Min (0.2% Offset) | Ultimate Tensile Strength Min | Elongation (% in 2") |
|---|---|---|
| 150,000 (1,035 MPa) | 180,000 (1,240 MPa) | 12 (min) |
Typical Short Time Tensile Properties as a Function of Temperature
Typical short time tensile properties as a function of temperature are shown here for material solution treated and aged as follows:
- Solution Treatment: 1800°F (982°C) 1 hour
- Precipitation Treatment: 1325°F (718°C) 8 hours, Furnace Cool at 100°F (55°C) per hour to 1150°F (621°C) 8 hours
