TECHNICAL INFORMATION FOR A286 PER PWA-S-5732
PWA-S-5732 is the Pratt & Whitney Aerospace standard for A286 stainless steel bar for use in high-temperature parts of aircraft engine construction. It is essentially the same as AMS 5732, specifying the properties of the corrosion- and heat-resistant alloy A286.
A286 is a high-temperature alloy consisting of iron, nickel, chromium, molybdenum, and titanium. These elements are known for improving the strength, oxidation resistance, and thermal stability of the alloy. A286 is an austenitic precipitation-hardenable alloy that complies with the properties of PWA-S-5732 and maintains good mechanical properties until 1300°F (704°C).
A286 stainless steel bar is often utilized for its high strength, good fabricability, and oxidation resistance in the construction of aircraft engine parts and turbines.
Is A286 a Stainless Steel?
Some companies list A286 under Nickel and some companies list A286 under Stainless Steel. Ultimately, It is an iron-nickel-chromium alloy with additions of molybdenum and titanium making it a super alloy that is in between those categories. As one of the austenitic alloys it maintains good strength and oxidation resistance at temperatures up to 1300ºF. Due to its high strength and excellent fabrication characteristics it performs like a Nickel alloy but has a similar density to that of Stainless Steel. Because of these characteristics, A286 is one of the most popular high temperature alloys.
