Nickel Waspaloy AMS 5708

AMS 5708 is the aerospace material specification covering Waspaloy (UNS N07001) bars, wire, forgings and rings supplied solution heat treated at 1975°F (1079°C). It’s the stock form of the creep-resistant Waspaloy route, which keeps useful strength at temperatures well above 1200°F (650°C).

What defines AMS 5708 is its higher 1975°F solution temperature, supplied without aging. The hotter solution treatment coarsens the grain, which gives the best creep and stress-rupture life of any Waspaloy condition. Leaving it unaged lets the buyer head, forge or machine the material first, and then run the 1550°F stabilization and 1400°F aging. Of the bar specs, AMS 5708 is the only one that also covers wire, which suits fastener heading.

Typical AMS 5708 uses:

• Headed turbine bolts, studs and nuts for sustained high-temperature load
• Stock for turbine blades, vanes and blade retainers
• Rings and forgings needing long creep life

For the same 1975°F route supplied fully stabilized and aged, see the companion specification AMS 5709.
