Inconel 718 Sheet & Coil

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)
