Stainless Steel A286 AMS 5736

AMS 5736 was the aerospace material specification covering A286 stainless steel (UNS S66286) bars, forgings, tubing and rings supplied solution heat treated at 1800°F (982°C), without aging. SAE has withdrawn it, but it’s still found on older drawings and in legacy purchasing systems.

What defines AMS 5736 today is that it’s the withdrawn, unaged version of the 1800°F route. Its role has passed to AMS 5731, which covers the same solution-treated condition with consumable-electrode melting for better cleanliness. Parts originally made from AMS 5736 were forged, formed or machined before aging, and the same approach works with AMS 5731 material. As with any spec change, check that your engineering or quality team approves the substitution.

Where AMS 5736 still shows up:

• Overhaul and spare parts for older turbine engines
• Legacy forging and ring-rolling orders
• Older material lists in MRO and repair stations

For the current equivalent, see AMS 5731. Full composition and properties are on the A286 stainless steel page. Tech Steel & Materials can help you source A286 for legacy AMS 5736 callouts. Request a quote and we’ll confirm the right current certification for your part.
