Stainless Steel A286 AMS 5732

AMS 5732 is the aerospace material specification covering A286 stainless steel (UNS S66286) bars, wire, forgings, rings and tubing. It’s consumable-electrode melted, solution treated at 1800°F (982°C) and precipitation heat treated, with a minimum tensile strength of 130 ksi and yield strength of 85 ksi.

What defines AMS 5732 is that it’s the ready-to-machine, creep-optimized A286. The mill has already finished the full heat treatment, so the material goes straight from stock to the machining center with no furnace step in your shop. Because it uses the 1800°F route, it gives up a little room-temperature strength compared with 1650°F material in exchange for better stress-rupture life above about 1000°F. It’s the most widely stocked aged A286 spec for hot-section hardware.

Typical AMS 5732 parts:

• Turbine wheels, spacers and blade retainers
• Hot-section bolts and studs where creep matters more than peak strength
• Afterburner parts, casings and support rings

For maximum room-temperature strength, see the companion 1650°F specification AMS 5737.
