TECHNICAL INFORMATION FOR A286 PER AMS 5731
A286 Stainless Steel per AMS 5731 is a solution treated specification of Stainless Steel A286. The treatment includes heating to 1800 °F (980 °C) for one hour, followed by oil or water quenching. AMS 5731 has many favorable properties, including excellent strength at high temperatures, excellent corrosion resistance up to 1300 °F (700 °C), and low-temperature non-magnetic strength, down to -320 °F (-196 °C).
Applications of AMS 5731
- AIRCRAFT COMPONENTS
Used in jet engine parts, industrial gas turbines, and superchargers, where high strength at extreme temperatures is essential. - CRYOGENIC AND NON-MAGNETIC PARTS
Ideal for tanks, piping, pumps, and heat exchangers in cryogenic environments requiring non-magnetic materials. - INDUSTRIAL USES
Applied in precision components subjected to high stress and repeated thermal cycling.
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.
