Frequently asked questions
What is Inconel 706 · UNS N09706?
Inconel 706 · UNS N09706 — Fe-Ni superalloys. Large turbine discs and generator retaining rings — more forgeable than 718
What is the maximum service temperature of N09706?
Typically about 700 °C; the practical limit depends on media, stress and design life — acceptance per the governing standard.
What is the tensile strength of N09706?
The specified minimum tensile strength is 1207 MPa for the main product form. Minima for other forms and sizes are listed under "Mechanical minima by form" on this page.
Which standards cover N09706?
SAE AMS 5605 706//1800°F, SAE AMS 5606 706//1750°F, SAE AMS 5701 7061800°F, SAE AMS 5702 7061750°F, SAE AMS 5703 706++
Where is N09706 typically used?
