Properties

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)

Solution Treated plus Precipitation Heat Treatment
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
